   4 [09:02] <shrini> Hello all
   5 [09:02] <shrini> So happy to meet you all here
   6 [09:03] <shrini> Here, let us explore the various options of package management in ubuntu
   7 [09:04] <shrini> One of the best feature that ubuntu provides is its package management
   8 [09:04] <shrini> When I was in windows world, I used to carry some 30 to 40 CDs with me always
   9 [09:04] <shrini> they were filled with various software
  10 [09:05] <shrini> I had my local collection of required software
  11 [09:05] <shrini> but the ubuntu linux changed the way we approach installing software in our systems
  12 [09:06] <shrini> Let us explore about installing and removing of various software in ubuntu linux
  13 [09:06] <shrini> using Graphical Tools and commandline tools
  14 [09:07] <shrini> First tool is "Ubuntu Software Center"
  15 [09:07] <shrini> It is available under the menu "Applications"
  16 [09:08] <shrini> Hope you all have ubuntu machines now
  17 [09:08] <shrini> Please open that software
  18 [09:09] <shrini> It is talking a little time to load
  19 [09:09] <shrini> It is there opened
  20 [09:09] <shrini> It is showing some departments
  21 [09:09] <shrini> What are they?
  22 [09:10] <shrini> Unlike Windows and Mac, Ubuntu linux provides tons and tons software
  23 [09:10] <shrini> It gives a central place where we can fetch required software
  24 [09:12] <shrini> That central place is available in the internet
  25 [09:12] <shrini> it is called as "repository"
  26 [09:13] <shrini> Ubuntu gives some default repositories to fetch the software
  27 [09:13] <shrini> we can add some extra repositories too.
  28 [09:13] <shrini> repository can be called as "repo" too
  29 [09:14] <shrini> The default repository is available at http://archive.canonical.com/ubuntu/dists/
  30 [09:14] <shrini> you can browse the available packages for all the ubuntu versions
  31 [09:14] <shrini> Let us come back to our "Ubuntu Software Center"
  32 [09:15] <shrini> The available software in the repositories are categorised into various departments
  33 [09:16] <shrini> Ubuntu is for all human beings
  34 [09:16] <shrini> so it provides software for various fields where computers can be used
  35 [09:17] <shrini> From Education, development, graphics, multimedia, research, office to games
  36 [09:17] <shrini> and more
  37 [09:17] <shrini> Let us explore the Graphics packages available
  38 [09:18] <shrini> I am clicking the "Graphics" department
  39 [09:18] <shrini> It gives some more categories like 3D, Drawing, Photography, Viewers etc
  40 [09:19] <shrini> Going into Photography
  41 [09:19] <shrini> It provides all the software required for digital photography management
  42 [09:19] <shrini> See the small green tick mark in the "Shotwell Photo Manager"
  43 [09:20] <shrini> It means that "Shotwell Photo Manager" is already installed in our computer
  44 [09:20] <shrini> We can install any of the software shown here
  45 [09:21] <shrini> Let us install "Gwenview"
  46 [09:21] <shrini> It is a nice Image viewer
  47 [09:21] <shrini> LEt us click on it
  48 [09:22] <shrini> It shows some little info with a button "install"
  49 [09:22] <shrini> Let us click the button "more info"

  53 [09:24] <shrini> Now let us click the button "install" shown in the same page
  54 [09:24] <shrini> Now it asks the password
  55 [09:25] <shrini> we need the administrator privileges to install any software in ubuntu
  56 [09:25] <shrini> The first user in ubuntu has the admin right and we can give the password
  57 [09:26] <shrini> if we have the admin permission, the screen goes to the next stage
  58 [09:26] <shrini> The blue bar shows the status as "installing"
  59 [09:27] <shrini> In the left panel, we can see a new item as "In progress (1)"
  60 [09:29] <shrini> After a while, it is finished the progress and it shows as "installed"
  61 [09:31] <shrini> the speed depends on the speed of Internet connection
  62 [09:32] <shrini> and the dependencies it has to download
  63 [09:32] <shrini> We can install any package like this
  64 [09:35] <shrini> Ubuntu provides such easiest process to install any software
  65 [09:36] <shrini> The same software center provides some "Featured" software in the home  page
  66 [09:38] <shrini> They are the best software referred by the ubuntu community to install and live happily
  67 [09:39] <shrini> they are popular, stable and feature rich software
  68 [09:40] <shrini> We can click on any already installed software and we can see the button "remove"
  69 [09:41] <shrini> we can uninstall the software by clicking the "remove" button
  70 [09:41] <shrini> It will ask for the password and will remove it
  71 [09:42] <shrini> Let us explore some advanced software called "Synaptic Package Manager"

  76 [09:45] <shrini> the right panel lists the software available at the selected department
  77 [09:45] <shrini> top right corner has a search box
  78 [09:45] <shrini> give some text there and see the result
  79 [09:46] <shrini> I give there as "thunderbird"
  80 [09:46] <shrini> It shows the results of the software related to the word "thunderbird"
  81 [09:47] <shrini> we can click on any software and select "Mark for Installation" in the menu
  82 [09:47] <shrini> I selected "thunderbird"
  83 [09:47] <shrini> Now, click the "Apply" button in the top panel
  84 [09:48] <shrini> another window pops up with some more details
  85 [09:48] <shrini> it shows the size of download, dependency package list etc
  86 [09:48] <shrini> I click "apply" button and it starts to download
  87 [09:49] <shrini> we can see the files being downloaded and installed automatically
  88 [09:49] <ClassBot> Fred55411 asked: Does KDE app have lots of dependencies when installed on Gnome system?
  89 [09:50] <shrini> yes. KDE apps will download the core packages to run the KDE apps
  90 [09:50] <shrini> we can run all the KDE apps in Gnome, after installing the required kde packages
  91 [09:51] <ClassBot> geekosopher asked: If installing a package requires removal of other already installed program, does Software Center warn the user that the other package will be removed?
  92 [09:51] <ClassBot> There are 10 minutes remaining in the current session.
  93 [09:53] <shrini> it will do that automatically
  94 [09:53] <shrini> synaptic and commandline tools will show the list of software installed and removed
  95 [09:53] <shrini> after we confirm only they start installing
  96 [09:54] <shrini> To remove any software using synaptic, we can click and select "Mrk for removal"
  97 [09:54] <shrini> "Mark for complete removal" will remove all the dependency software too
  98 [09:56] <shrini> we can edit or add repositories in "Settings->Repositories" in synaptic
  99 [09:56] <ClassBot> There are 5 minutes remaining in the current session.
 100 [09:56] <shrini> Let us explore some commandline tools
 101 [09:56] <shrini> open a terminal
 102 [09:56] <shrini> apt-cache search <name>
 103 [09:56] <shrini> to search the software related to the "name?
 104 [09:57] <shrini> apt-cache search thunderbird

 110 [09:57] <shrini> to uninstall any software
 111 [09:58] <shrini> sudo apt-get remove thunderbird
 112 [09:58] <ClassBot> Fred55411 asked: You said "left panel gives various departments same as software center" but software center's seem more "friendly" and less extensive. Do you concur?
 113 [09:59] <shrini> Yes. software center is more user friendly
 114 [09:59] <shrini> My old dad loves it very much then synaptic
 115 [09:59] <shrini> Ubuntu is always making our life much easier
