Download1 00:00:01,171 --> 00:00:05,179 This is Alan Pope with the ninth screencast in the Ubuntu Month of Screencasts. 2 00:00:05,302 --> 00:00:08,122 All the screencasts in this month can be downloaded from our website, 3 00:00:08,222 --> 00:00:11,720 which is screencasts.ubuntu.com 4 00:00:12,423 --> 00:00:17,529 In this screencast we are going to look at installing Ubuntu using a live CD. 5 00:00:18,585 --> 00:00:22,506 I've called this part 1 because we are going to look at installing via different methods 6 00:00:22,606 --> 00:00:24,863 in subsequent screencasts. 7 00:00:24,963 --> 00:00:28,319 Now there's different version of Ubuntu we've talked about in other screencasts, 8 00:00:28,419 --> 00:00:31,709 there's Ubuntu, Edubuntu, Xubuntu and Kubuntu 9 00:00:31,892 --> 00:00:34,899 and the installation process is much the same for all of them. 10 00:00:35,014 --> 00:00:36,836 But the end result is slightly different, 11 00:00:36,936 --> 00:00:39,458 you get a different look and feel for each of them. 12 00:00:39,558 --> 00:00:43,801 But pretty much everything I say throughout this screencast holds true for each of them. 13 00:00:43,988 --> 00:00:49,990 You can get hold of CDs and images of CDs for all of the versions of Ubuntu. 14 00:00:50,134 --> 00:00:55,007 and go through pretty much the same process to get an install. 15 00:00:55,496 --> 00:00:59,632 The version of Ubuntu we are going to use is 7.10 Gutsy Gibbon. 16 00:00:59,732 --> 00:01:03,674 Now, this version isn't actually out yet, it's still under development, 17 00:01:03,963 --> 00:01:09,622 So this is released in October, which is about a month from now. 18 00:01:09,963 --> 00:01:13,939 I wouldn't recommend that general users install version 7.10, 19 00:01:14,039 --> 00:01:17,580 because it is changing a lot, it's under development and things break now and then. 20 00:01:17,680 --> 00:01:21,524 So I strongly recommend you install 7.04 or 6.06 21 00:01:21,624 --> 00:01:24,799 or whatever is the current stable version 22 00:01:24,899 --> 00:01:27,288 at the time that you're watching this screencast. 23 00:01:27,388 --> 00:01:32,710 And right now that is 7.04 Feisty Fawn or 6.10 or 6.06 24 00:01:33,747 --> 00:01:38,388 You can get hold of Ubuntu from the Ubuntu website, which is ubuntu.com 25 00:01:38,569 --> 00:01:41,948 There's a link on the left hand side to Get Ubuntu. 26 00:01:42,182 --> 00:01:45,267 and you can download it directly from the website 27 00:01:45,434 --> 00:01:50,747 Alternatively you can order a CD and have it shipped to you. 28 00:01:50,847 --> 00:01:53,166 And there's a separate website for this 29 00:01:53,266 --> 00:01:57,014 There is actually a link from the ubuntu.com that says request free CDs 30 00:01:57,155 --> 00:02:00,844 and you can also get them from ShipIt, shipit.ubuntu.com, 31 00:02:01,013 --> 00:02:04,344 where you can order a number of CDs 32 00:02:04,903 --> 00:02:09,527 The CD I am using I actually downloaded from ubuntu.com and burned. 33 00:02:09,725 --> 00:02:13,256 And then inserted into a PC and booted up. 34 00:02:13,356 --> 00:02:18,825 And what you will see next is what happens when you first boot off of the Ubuntu live CD 35 00:02:19,468 --> 00:02:22,024 It's also called the Desktop CD. 36 00:02:22,505 --> 00:02:24,673 So this is the menu you see and you can 37 00:02:24,773 --> 00:02:26,941 navigate through the menu with the up and down arrows 38 00:02:27,041 --> 00:02:29,161 Press enter to select the option you want 39 00:02:29,261 --> 00:02:31,968 There are also some function keys along the bottom. 40 00:02:32,349 --> 00:02:35,939 If we press F1, we get some on-line help, 41 00:02:36,039 --> 00:02:38,097 It tells us what the function keys do 42 00:02:38,197 --> 00:02:41,975 and also tells you when this CD image was created. 43 00:02:42,075 --> 00:02:46,794 F2 allows you to choose the language under which the installer will run. 44 00:02:47,079 --> 00:02:49,833 F3 allows you to change the keyboard layout 45 00:02:49,933 --> 00:02:53,929 and I'm going to change it to United Kingdom, because that's where I am. 46 00:02:54,204 --> 00:02:59,926 F4 allows you to change the video resolution. 47 00:03:00,026 --> 00:03:03,220 This might be useful if your video card is a bit quirky 48 00:03:03,347 --> 00:03:06,660 and doesn't like the resolution that the system boots up in. 49 00:03:06,889 --> 00:03:09,721 And F5 gives you some accessibility options. 50 00:03:09,821 --> 00:03:14,605 For example, there's a high contrast option if your eyesight is not fantastic, 51 00:03:14,705 --> 00:03:17,242 for example you might want to use that. 52 00:03:17,563 --> 00:03:19,585 F6 we will come back to in just a minute. 53 00:03:19,787 --> 00:03:23,203 So the list of options we've got, the first one is "Start or install Ubuntu". 54 00:03:23,303 --> 00:03:25,834 "Start" means boot in to the live environment and use it, 55 00:03:25,934 --> 00:03:29,349 "install" means install it to the hard drive and you can do both with that option. 56 00:03:29,449 --> 00:03:33,900 The second option is useful if you have a dodgy video card that doesn't work very well 57 00:03:34,449 --> 00:03:39,879 with the Ubuntu system, so maybe you could use that to boot safe graphics mode. 58 00:03:40,203 --> 00:03:44,585 "Install with a driver update CD" is useful if you have very very new bit of hardware like 59 00:03:44,685 --> 00:03:50,123 a very new disk controller that's not supported by the standard process. 60 00:03:50,567 --> 00:03:54,900 "OEM install" is useful for people who are building systems for other people, 61 00:03:55,226 --> 00:03:57,543 Original Equipment Manufacturers 62 00:03:57,727 --> 00:04:00,418 and that allows the end user to put in their own details 63 00:04:00,518 --> 00:04:02,506 like their name and their password, 64 00:04:02,606 --> 00:04:05,039 on the first time they boot it up. 65 00:04:05,148 --> 00:04:08,205 "Check CD for defects", well it's pretty obvious what that does, 66 00:04:08,305 --> 00:04:12,610 it checks to make sure the CD is correct. 67 00:04:13,027 --> 00:04:18,618 "Memory test" is useful to diagnose problems with memory in the computer, 68 00:04:18,718 --> 00:04:22,478 which often plague computer users. 69 00:04:23,178 --> 00:04:27,674 And the last one is "Boot from first hard disk" is useful if you have messed up the 70 00:04:27,774 --> 00:04:31,010 boot sector on your first hard disk. 71 00:04:32,153 --> 00:04:35,029 If I press F6 you can see these options appear down the bottom. 72 00:04:35,129 --> 00:04:39,197 Now these are useful in that you can change these 73 00:04:39,378 --> 00:04:43,448 and for example someone might recommend to diagnose a problem 74 00:04:43,548 --> 00:04:47,011 you type in an extra parameter, which you could just type on the end of that line. 75 00:04:47,633 --> 00:04:52,145 or they might ask for more information by getting rid of the "quiet" and the "splash" 76 00:04:52,340 --> 00:04:55,570 I'm just going to boot normally, so I will just press enter. 77 00:04:55,986 --> 00:04:59,866 Now when you press enter you get this bouncing orange bar as it boots up. 78 00:05:00,105 --> 00:05:03,848 It takes a little while, I've kind of skipped some time now, 79 00:05:03,948 --> 00:05:08,728 so we're not going to sit and watch that bouncing backwards and forwards for too long. 80 00:05:09,145 --> 00:05:12,150 Now it's worth noting that we are booting off of a CD 81 00:05:12,250 --> 00:05:14,577 and we're running off of a CD, 82 00:05:14,677 --> 00:05:19,278 so if it feels a bit slow, a bit sluggish that's understandable, 83 00:05:19,378 --> 00:05:22,353 because you're loading all of your programs from 84 00:05:22,453 --> 00:05:25,422 a compressed image that's on a slow device. 85 00:05:25,522 --> 00:05:29,594 A CD is a relatively slow device compared to a hard disk for example. 86 00:05:29,694 --> 00:05:34,627 So don't think that it's indicative of how fast the system will perform 87 00:05:34,727 --> 00:05:37,163 when you are using it off of a CD. 88 00:05:37,263 --> 00:05:41,610 It will be much faster once you have installed Ubuntu on to your hard disk. 89 00:05:42,841 --> 00:05:46,676 Once it's finished making the progress across the screen, 90 00:05:46,776 --> 00:05:49,676 you will eventually get the desktop. 91 00:05:49,812 --> 00:05:51,824 Now in order to fit this on the screen, 92 00:05:51,924 --> 00:05:55,438 I've had to crop about 80 pixels from the bottom of the screen. 93 00:05:55,609 --> 00:05:58,063 So there's normally a little panel at the bottom of the screen, 94 00:05:58,163 --> 00:06:02,038 you can't see it because I had to crop that so that it fits. 95 00:06:07,207 --> 00:06:10,524 So eventually we get our desktop, it doesn't take too long, 96 00:06:10,624 --> 00:06:15,479 it's only a couple of minutes or so, on a relatively modern PC. 97 00:06:17,457 --> 00:06:21,247 If you have an slower, older PC, then you might want to try Xubuntu instead. 98 00:06:21,347 --> 00:06:25,336 Xubuntu starts with an X and has a more lightweight windowing system. 99 00:06:25,486 --> 00:06:28,250 Okay so we are booted up and over here you can see there is an icon 100 00:06:28,350 --> 00:06:30,556 to install Ubuntu on to the hard drive. 101 00:06:30,656 --> 00:06:33,527 We can actually just use the system as it is, 102 00:06:33,818 --> 00:06:37,383 booting directly from the CD and use the applications that are installed 103 00:06:37,517 --> 00:06:40,903 But as the subject of this screencast is to install Ubuntu, 104 00:06:41,003 --> 00:06:43,557 I am going to run the installer. 105 00:06:44,187 --> 00:06:45,854 Now the installer gives us a warning, 106 00:06:45,954 --> 00:06:50,662 reminding us that this is not the final release of version 7.10 107 00:06:50,779 --> 00:06:53,756 So you shouldn't really use it on a productive system. 108 00:06:53,884 --> 00:06:57,104 It also recommends that you take a full backup of any valuable data. 109 00:06:57,257 --> 00:07:01,753 Now I'm going to be installing on a completely blank, brand new 100GB disk, 110 00:07:01,853 --> 00:07:05,412 so there's nothing on it, I'm happy that that's okay. 111 00:07:05,805 --> 00:07:09,005 When you press forward you have the option of going to the release notes 112 00:07:09,105 --> 00:07:12,943 and I have Internet access here, the little icon in the top right is the Network Manager 113 00:07:13,043 --> 00:07:15,061 that says I've got network access. 114 00:07:15,161 --> 00:07:17,955 So I could click this button and it would fire up the web browser 115 00:07:18,055 --> 00:07:20,117 and I could view the release notes for this version, 116 00:07:20,217 --> 00:07:22,882 but I'm not going to do that. 117 00:07:24,739 --> 00:07:29,431 I can choose the language that I want the installer to run in and click forward. 118 00:07:31,351 --> 00:07:35,414 The choose the region that I am in and the nearest city to me. 119 00:07:35,514 --> 00:07:39,880 This is so that we can get the time zone and clock correct. 120 00:07:40,071 --> 00:07:42,118 So I click on London, which is the nearest city to me 121 00:07:42,218 --> 00:07:46,060 and you can see it has chosen BST, which is my local time zone 122 00:07:46,338 --> 00:07:48,914 and the current time is correct. 123 00:07:49,860 --> 00:07:53,946 Click forward and now it asks me what keyboard layout I'm using. 124 00:07:54,100 --> 00:07:56,592 Notice it's picked up United Kingdom, 125 00:07:56,692 --> 00:07:59,581 because of the options I've chosen earlier on. 126 00:07:59,830 --> 00:08:03,785 And there may be multiple keyboard layouts within your region, 127 00:08:04,047 --> 00:08:07,455 and you can try them out by typing characters in here. 128 00:08:07,555 --> 00:08:10,604 You can try various characters that you know 129 00:08:10,704 --> 00:08:13,689 are sometimes on the wrong place on your keyboard, 130 00:08:13,789 --> 00:08:15,797 if you have the wrong layout. 131 00:08:15,897 --> 00:08:20,368 and then choose forward when you are happy with the layout you've got. 132 00:08:21,966 --> 00:08:25,895 Now it starts the partitioner, which is thing that a lot of new people to 133 00:08:25,995 --> 00:08:29,170 Linux and Ubuntu have trouble with. 134 00:08:29,411 --> 00:08:31,619 So we will cover this in a little bit of detail. 135 00:08:31,740 --> 00:08:36,005 Now remember I've got one 100GB disk, it's a completely blank disk. 136 00:08:36,167 --> 00:08:40,762 and the defaults I have here is to wipe the entire disk. 137 00:08:40,862 --> 00:08:45,318 and for Ubuntu to partition the disk and use that entire disk. 138 00:08:45,443 --> 00:08:48,672 The second option is manual partitioning, which is what we are going to use. 139 00:08:48,803 --> 00:08:50,821 There is actually a third option that appears, 140 00:08:50,921 --> 00:08:52,954 if you've already got an operating system installed. 141 00:08:53,054 --> 00:08:55,002 If I for example have Windows on this system, 142 00:08:55,102 --> 00:08:59,152 It would give me the option of resizing the Windows partition down. 143 00:08:59,337 --> 00:09:01,376 I am going to use manual. 144 00:09:01,560 --> 00:09:03,166 Now when I choose manual and go forward, 145 00:09:03,266 --> 00:09:06,961 you can see here, it notes the device that I have is /dev/sda. 146 00:09:07,061 --> 00:09:09,322 sda means the first hard disk. 147 00:09:09,422 --> 00:09:12,341 a being the first one, b being the second and so on. 148 00:09:12,484 --> 00:09:17,163 Now this is a brand new clean hard disk, so I need to create a new partition table, 149 00:09:17,582 --> 00:09:20,074 because this disk has never had any information on it. 150 00:09:20,633 --> 00:09:23,852 So I hit the new partition table button and then click continue. 151 00:09:23,952 --> 00:09:27,557 You wouldn't have to this if the disk had ever been used before 152 00:09:27,874 --> 00:09:30,471 or it had a partition table already on it. 153 00:09:30,653 --> 00:09:34,022 So now we have, sda has a chunk of free space. 154 00:09:34,122 --> 00:09:37,772 and it's about 100GB of free space. 155 00:09:38,050 --> 00:09:40,671 Now I get the option to create a new partition. 156 00:09:40,821 --> 00:09:44,049 Now in the text just below that it tells you what it recommends 157 00:09:44,149 --> 00:09:49,377 a 2GB root partition, for / being the root mount point. 158 00:09:49,549 --> 00:09:51,347 and some swap as well. 159 00:09:51,447 --> 00:09:55,301 Now the default is to use the entire disk, starting from the beginning of the disk. 160 00:09:55,605 --> 00:09:59,763 Now we will change this size here, it's measured in Megabytes 161 00:10:00,454 --> 00:10:05,080 I'll change that and make it smaller, I'll make it 10GB or something like that. 162 00:10:05,207 --> 00:10:07,848 You can choose whether the partition sits at the beginning, 163 00:10:07,948 --> 00:10:09,947 the front of the disk or at the end of the disk. 164 00:10:10,075 --> 00:10:12,986 And also the partition type, the default is EXT3, 165 00:10:13,086 --> 00:10:15,069 which is a journaling file system. 166 00:10:15,204 --> 00:10:18,689 It's pretty reliable, robust and used very widely. 167 00:10:18,852 --> 00:10:22,745 EXT2 is another variant of EXT3 without the journaling. 168 00:10:23,260 --> 00:10:28,498 Other options include Reiserfs, which is going down in popularity at the moment. 169 00:10:29,010 --> 00:10:32,409 JFS. XFS is popular in media center computers, 170 00:10:32,509 --> 00:10:36,459 where you have very large files, like TV programs for example. 171 00:10:36,925 --> 00:10:41,118 FAT32 is popular on Windows and also with USB sticks 172 00:10:41,218 --> 00:10:44,646 and USB hard drives that you want to interchange between 173 00:10:44,746 --> 00:10:46,906 Windows and non-Windows platforms. 174 00:10:47,006 --> 00:10:48,865 I'm just going to choose EXT3 though. 175 00:10:49,002 --> 00:10:51,050 And you'll notice there are no mount points defined. 176 00:10:51,150 --> 00:10:53,786 So the mount point I'm going to use is / 177 00:10:53,886 --> 00:10:57,639 which is root, the top level of the disk hierarchy. 178 00:10:57,910 --> 00:11:01,139 And I'm going to change the amount of size, in MBs, 179 00:11:01,494 --> 00:11:05,901 so that it's not 100GB, because that's too much. 180 00:11:06,362 --> 00:11:09,252 I'm just going to give it 10GB or there abouts. 181 00:11:09,467 --> 00:11:13,501 I've just lopped the last number off, so it makes it roughly 10GB. 182 00:11:14,277 --> 00:11:19,134 And when I hit Ok, you can see there, it does a little bit of a calculation 183 00:11:20,591 --> 00:11:24,367 And we should see the first partition, the first partition on the first disk. 184 00:11:24,467 --> 00:11:29,454 So the first disk is /dev/sda and the first partition will be number 1. 185 00:11:29,724 --> 00:11:33,576 So it should be, /dev/sda1 will be the first partition. 186 00:11:33,676 --> 00:11:37,658 You can see there it's a 10GB partition, it needs formatting, 187 00:11:37,758 --> 00:11:41,391 it's going to be mounted as root, which is that slash (/). 188 00:11:41,491 --> 00:11:45,646 And the partition type is EXT2, it's going to be formatted as a... 189 00:11:45,746 --> 00:11:50,588 Err sorry, EXT3. It's going to be formatted as an EXT3 partition, 190 00:11:50,710 --> 00:11:55,098 And we have got ~90GB of free space, so let's create another partition, 191 00:11:55,236 --> 00:11:59,871 Now the notes down here says it needs a swap partition of at least 256 MB 192 00:12:00,139 --> 00:12:03,527 Swap is (in simplistic terms) an extension 193 00:12:03,627 --> 00:12:06,766 of the physical memory you have in your computer. 194 00:12:06,866 --> 00:12:09,740 So I'm just going to use 1GB swap, 195 00:12:09,840 --> 00:12:12,775 This machine has 1GB RAM, so I'm going to give it 1 GB of swap. 196 00:12:12,979 --> 00:12:16,578 Depends on who you ask, some people say you should have twice the amount of RAM as swap, 197 00:12:16,678 --> 00:12:19,380 some people say half, some people say none. 198 00:12:19,859 --> 00:12:22,887 I'm not going to go in to that, I'll just create one of the same amount. 199 00:12:23,290 --> 00:12:27,679 So now that I've created a swap part you can see the mount point is blank, 200 00:12:27,779 --> 00:12:32,542 because I don't need to mount that at a certain point in the directory tree. 201 00:12:34,214 --> 00:12:36,705 So we should have a second partition now, 202 00:12:39,082 --> 00:12:41,439 which will be /dev/sda2 and that will be swap. 203 00:12:41,688 --> 00:12:46,973 Now that's all I need to actually install Ubuntu is a root partition and a swap partition. 204 00:12:47,073 --> 00:12:50,513 But I'm going to create a third partition to put all of my files in. 205 00:12:50,613 --> 00:12:53,066 So I'm going to have 10GB root, that's for all the system files, 206 00:12:53,166 --> 00:12:55,169 libraries and all that kind of stuff. 207 00:12:55,269 --> 00:12:58,804 But I'm also going to have another partition for my home directory, 208 00:12:58,904 --> 00:13:00,949 which is where all the bulk of my data will be. 209 00:13:01,179 --> 00:13:05,544 All my documents and TV programs that I have recorded 210 00:13:05,664 --> 00:13:08,764 and audio files I may have downloaded. 211 00:13:08,864 --> 00:13:13,715 So I've got a nice big chunk of space there, ~90GB or so. 212 00:13:14,863 --> 00:13:17,801 and I'm going to make that EXT3 213 00:13:18,197 --> 00:13:22,835 and it's going to be mounted as /home. 214 00:13:22,998 --> 00:13:25,567 Which means that all the users on this system, 215 00:13:25,667 --> 00:13:28,181 their home directories will be under that path. 216 00:13:28,281 --> 00:13:34,047 So there will be ~96GB of space to share amongst all my users. 217 00:13:34,147 --> 00:13:37,569 And the system gets 10GB for it's use. 218 00:13:39,374 --> 00:13:44,115 Of course this can be re-configured later on and you could re-size things later on. 219 00:13:44,223 --> 00:13:46,296 But this would be a good start. 220 00:13:46,401 --> 00:13:50,717 There's an extra benefit of this, which is I could re-install the operating system on sda1 221 00:13:50,817 --> 00:13:53,797 and that won't touch all of my files that are in my home directory, 222 00:13:53,897 --> 00:13:58,493 which will be on sda3, the third partition that it is about to create. 223 00:14:05,515 --> 00:14:10,750 So there we have it, we now have three partitions sda1, sda2 and sda3. 224 00:14:10,977 --> 00:14:13,489 sda1 is my root, sda2 is swap 225 00:14:13,589 --> 00:14:17,849 and sda3 is my home directories with plenty of space. 226 00:14:17,949 --> 00:14:21,851 The two EXT3 partitions are going to be formatted. 227 00:14:24,833 --> 00:14:30,173 So it's not too difficult, so long as you get the sizes right and the right mount points. 228 00:14:30,608 --> 00:14:32,546 Let's move on. 229 00:14:34,148 --> 00:14:38,766 Now the migration tool is useful if you already have Windows installed on this PC, 230 00:14:38,866 --> 00:14:43,922 I don't, but if I did it would give me the opportunity of migrating things like email, 231 00:14:44,022 --> 00:14:51,277 browser favorites and other documents from the My Documents folder and so on, 232 00:14:51,377 --> 00:14:56,090 on the Windows partition and bring those into my Ubuntu partition. 233 00:14:56,393 --> 00:14:59,284 It's very good Migration tool, very useful. 234 00:15:00,286 --> 00:15:03,491 Next it wants to know my name, now this is going to be the first person, 235 00:15:03,591 --> 00:15:06,313 the first user id that gets created on the system 236 00:15:06,459 --> 00:15:11,631 and this will have some administrative rights, which could be changed later on. 237 00:15:11,781 --> 00:15:13,773 So I'll fill in a username and password. 238 00:15:13,873 --> 00:15:16,333 You can add additional users later as well, of course. 239 00:15:16,525 --> 00:15:18,796 This will just be the first user. 240 00:15:19,233 --> 00:15:21,425 And we give the computer a name. 241 00:15:21,560 --> 00:15:23,653 So this is going to be my hostname on the network, 242 00:15:23,753 --> 00:15:26,847 so this is how my computer appears on the network. 243 00:15:27,641 --> 00:15:29,886 Click next. 244 00:15:32,663 --> 00:15:34,739 And that's all the questions it asks you, 245 00:15:34,839 --> 00:15:37,833 The rest is just a summary of what it says it's going to do, 246 00:15:37,933 --> 00:15:40,326 so at the top here we can see the language settings, 247 00:15:40,426 --> 00:15:42,565 the user that it's going to create and the region. 248 00:15:42,665 --> 00:15:46,014 The migration assistant isn't being used because I don't have Windows on this machine. 249 00:15:46,114 --> 00:15:47,777 It's a blank disk. 250 00:15:47,877 --> 00:15:50,616 And then it gives a summary of what it's going to do to the disk. 251 00:15:50,716 --> 00:15:55,342 So we're going to have three partitions /, swap and /home. 252 00:15:55,808 --> 00:15:57,956 And there's an Advance button over here, 253 00:15:58,056 --> 00:16:00,056 where we can specify the boot loader. 254 00:16:00,156 --> 00:16:03,619 The boot loader is a program called Grub, it's the menu you first see, 255 00:16:03,719 --> 00:16:07,164 Sometimes you don't see it because it counts down for a few seconds and then disappears. 256 00:16:07,299 --> 00:16:10,604 But it's the first thing you see when you boot up your Ubuntu system. 257 00:16:10,704 --> 00:16:14,029 and you can choose which disk you install that boot loader on. 258 00:16:14,129 --> 00:16:17,138 So if you had multiple disks you can choose which disk it goes on, 259 00:16:17,238 --> 00:16:19,662 hd0 being the first disk. 260 00:16:20,067 --> 00:16:22,966 There's also an option here to switch on the popularity contest. 261 00:16:23,282 --> 00:16:26,030 Popularity Contest or sometimes just known as popcon, 262 00:16:26,331 --> 00:16:29,926 is a tool that records which applications you have 263 00:16:30,026 --> 00:16:33,421 and submits that back to Ubuntu, so that they can 264 00:16:33,556 --> 00:16:37,852 well basically know the popularity of the applications that users are using. 265 00:16:38,453 --> 00:16:42,629 It doesn't really record what you use, just which ones you install. 266 00:16:43,816 --> 00:16:48,162 So I've ticked that box and I click forward and now the installation starts. 267 00:16:48,262 --> 00:16:50,860 Now I'm skipping forward in time a little bit here 268 00:16:51,011 --> 00:16:53,084 I'm cheating a little. 269 00:16:53,264 --> 00:16:56,889 Something that's worth noting is that you can go off and use the system. 270 00:16:56,989 --> 00:17:00,880 But it will slow the system down a little bit, while you're installing and using it. 271 00:17:01,090 --> 00:17:04,114 Another thing that's useful to know is this package manager here, 272 00:17:04,214 --> 00:17:08,630 you can install additional software before you start the installtion to disk. 273 00:17:08,826 --> 00:17:11,850 So you're running off of a read only medium, the CD, 274 00:17:11,950 --> 00:17:14,494 you can actually software in to memory 275 00:17:14,594 --> 00:17:17,844 and then start the installation on to the hard disk. 276 00:17:17,944 --> 00:17:23,446 And whatever you install into memory will then be installed on the hard disk. 277 00:17:23,591 --> 00:17:25,544 Which is quite a useful feature. 278 00:17:25,644 --> 00:17:29,795 So what will happen is, if we go and look at the file system 279 00:17:30,096 --> 00:17:34,437 that's currently in use on this live running environment. 280 00:17:34,797 --> 00:17:37,516 If I double-click the file system option, 281 00:17:37,616 --> 00:17:40,130 you can see all these folders here contain the files 282 00:17:40,230 --> 00:17:43,710 that will be dropped on to the hard disk. 283 00:17:43,810 --> 00:17:47,400 And if I were to run the Synaptic Package Manager 284 00:17:47,500 --> 00:17:51,561 and install software, it would be installed into those folders. 285 00:17:51,711 --> 00:17:55,601 and then those folders would be dropped on to the hard disk, 286 00:17:55,701 --> 00:17:59,041 and then I would end up with that software kind of pre-installed if you like. 287 00:17:59,161 --> 00:18:02,977 So now it's going through formatting the partitions. 288 00:18:03,202 --> 00:18:08,475 There are a little large so it's going to take a little while to format those. 289 00:18:10,217 --> 00:18:13,016 Now of course you don't have to have a separate /home partition, 290 00:18:13,116 --> 00:18:18,659 but as I said it useful to do that, because later on I could decide to 291 00:18:18,989 --> 00:18:21,213 change the version of Ubuntu I'm using 292 00:18:21,318 --> 00:18:23,471 or even completely change distribution. 293 00:18:23,601 --> 00:18:26,310 I might decide I don't like Ubuntu and I want to change to 294 00:18:26,410 --> 00:18:29,083 Debian or Red Hat or Fedora or something else. 295 00:18:29,183 --> 00:18:32,754 And you could install the replacement operating system 296 00:18:32,854 --> 00:18:34,987 in the first partition, the root partition 297 00:18:35,087 --> 00:18:38,772 and it would leave your /home partition alone. 298 00:18:38,872 --> 00:18:40,875 It wouldn't touch your /home partition. 299 00:18:40,975 --> 00:18:43,849 and the benefit of that is of course all your data stays intact. 300 00:18:44,000 --> 00:18:45,982 All your settings stay intact as well. 301 00:18:46,082 --> 00:18:49,572 So if you install software under that new distribution, 302 00:18:49,738 --> 00:18:54,109 It should just carry on working, subject to some limitations, 303 00:18:54,349 --> 00:18:56,968 as it did under your previous installation. 304 00:18:57,068 --> 00:18:59,291 It's a very useful way of partitioning the disk up. 305 00:18:59,391 --> 00:19:03,457 Some people partition the disk even further and have multiple partitions for 306 00:19:03,557 --> 00:19:08,123 /, /var, /tmp. /home and so on and so on. 307 00:19:08,349 --> 00:19:13,396 But these days with disks being very large and plenty of space. 308 00:19:13,516 --> 00:19:15,559 That's not so common. 309 00:19:15,679 --> 00:19:19,169 One of the reasons people tend to do it is to ensure that for example 310 00:19:19,269 --> 00:19:24,216 a log file that builds up in the /var directory doesn't cause the system 311 00:19:24,316 --> 00:19:29,033 to completely run out of disk space and then cause problems for the user. 312 00:19:31,511 --> 00:19:34,891 So we're getting towards the end of the installation now. 313 00:19:35,237 --> 00:19:38,301 Depending upon the hardware specification of your PC, 314 00:19:38,401 --> 00:19:40,644 this could take up to maybe half an hour, 315 00:19:40,744 --> 00:19:44,855 maybe even an hour on a fairly slow system. 316 00:19:44,955 --> 00:19:49,016 You need to have really at least 256MB of RAM 317 00:19:49,116 --> 00:19:52,391 to be able to boot off the live environment and install. 318 00:19:52,491 --> 00:19:56,011 Ideally you would have more than 256MB of RAM, 319 00:19:56,251 --> 00:19:58,684 because you need to have the live environment running 320 00:19:58,784 --> 00:20:01,994 and this installer program, which is called Ubiquity. 321 00:20:02,094 --> 00:20:05,294 That's the installer that we're running right now. 322 00:20:06,405 --> 00:20:09,199 If you have less than 256MB of RAM, 323 00:20:09,299 --> 00:20:11,533 then you might want to try the alternate CD, 324 00:20:11,633 --> 00:20:14,922 which we will cover in the next screencast. 325 00:20:15,508 --> 00:20:17,511 So that's it, the installation has finished, 326 00:20:17,611 --> 00:20:20,600 if we want to we can continue to use the live environment. 327 00:20:20,705 --> 00:20:24,551 If you are in the middle of editing documents and so on, you can just carry on doing so. 328 00:20:24,716 --> 00:20:27,560 and you could save those documents on to a USB stick 329 00:20:27,660 --> 00:20:31,956 or save them on to the local partitions that you have now formatted. 330 00:20:33,083 --> 00:20:36,693 Alternatively you could, if you haven't got any documents open, 331 00:20:36,793 --> 00:20:40,578 or any files open you can just hit the Restart now button. 332 00:20:40,849 --> 00:20:43,838 And it will shutdown, ask you to eject the CD 333 00:20:43,938 --> 00:20:47,638 and then when you reboot the first thing you should see graphic-wise 334 00:20:47,738 --> 00:20:49,738 is the logon screen, which is this screen here. 335 00:20:49,838 --> 00:20:54,683 I type in my user name and password and hopefully we should get the desktop up. 336 00:20:55,074 --> 00:20:58,123 There we go and it's much quicker than when it boots off of the CD, 337 00:20:58,223 --> 00:21:02,389 because we are now booting off the hard drive, which is orders of magnitude faster. 338 00:21:04,747 --> 00:21:09,284 So this is booted now to version 7.10 Gutsy. 339 00:21:09,644 --> 00:21:12,954 and here we've got our Applications, Places and System menus, 340 00:21:13,054 --> 00:21:15,938 which we have covered in previous screencasts. 341 00:21:17,245 --> 00:21:19,578 And over on the right-hand side 342 00:21:19,678 --> 00:21:22,357 we've got a notification that there's some software updates. 343 00:21:22,457 --> 00:21:26,453 So the CD that I downloaded, since that CD was pressed 344 00:21:26,753 --> 00:21:31,155 there have been, how many? 96 updates made to Ubuntu. 345 00:21:31,255 --> 00:21:33,948 Because this is the development version, it's changing rapidly. 346 00:21:34,129 --> 00:21:36,802 There's a fast user switching tool there, 347 00:21:37,103 --> 00:21:41,314 we have the little applet for doing searches, 348 00:21:41,414 --> 00:21:43,487 we have Network Manager, 349 00:21:43,742 --> 00:21:47,127 sound control and all kinds of other really groovy stuff 350 00:21:47,227 --> 00:21:50,231 that we will cover in other screencasts. 351 00:21:52,094 --> 00:21:58,283 So that's basically it for installing Ubuntu from a live CD. 352 00:21:59,154 --> 00:22:01,978 I hope that was useful. 353 00:22:02,488 --> 00:22:05,373 You can find further screencasts on our website, 354
