The Ubuntu team is happy to bring you the latest and greatest software the Open Source community has to offer. This is their latest result, the Ubuntu 9.10 Release Candidate, which brings a host of exciting new features.
Upgrading from Ubuntu 9.04
To upgrade from Ubuntu 9.04 on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '9.10' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 9.04 on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions.
Get it while it's hot. ISOs and torrents are available at:

New features since Ubuntu 9.04
As part of our boot performance work, we have now transitioned to Upstart native jobs, to let users get to their desktop faster after boot. Upstart is written by Scott James Remnant.
Ubuntu 9.10 RC includes the Ubuntu Software Center, developed by Michael Vogt, replacing 'Add/Remove' in the Applications menu.
Ubuntu 9.10 RC includes the latest GNOME 2.28 desktop environment with a number of great new features:
The gdm 2.28 login manager by William Jon McCann is a complete rewrite compared to the version in earlier Ubuntu releases, permitting a more integrated login experience.
Evince, the GNOME document viewer, now ships with an enforcing AppArmor profile. This greatly increases security by protecting you against flaws in the historically problematic PDF and image libraries. Users who use a non-standard location for their home directory will need to adjust the home tunable in /etc/apparmor.d/tunables/home. This profile has been developed by the Ubuntu Security team.

Application development with Quickly
Quickly, by Rick Spencer and Didier Roche, makes it easy for developers to make new applications for Ubuntu, and to share those application with other Ubuntu users via .deb packages or personal package archives.
Ubuntu Enterprise Cloud Images
Ubuntu 9.10 RC includes images for common use on Ubuntu Enterprise Cloud (UEC) and Amazon's EC2. You can try out the latest Ubuntu 9.10 server image instantly on EC2 using a preconfigured AMI, or download an image and put it into your own Ubuntu Enterprise Cloud. For information on using UEC images on Amazon EC2, see the EC2 Starter's Guide.
Ubuntu 9.10 RC ships with Ubuntu One by default. Ubuntu One is your personal cloud. You can use it to back up, store, sync and share your data with other Ubuntu One users.
Ubuntu One gives all features and 2 GB of essential storage to everyone. Synchronize files, contacts, and Tomboy notes across all of your Ubuntu computers and to the cloud. More space is available with a monthly subscription.
Ubuntu One project information is available on Launchpad.
Linux kernel 2.6.31
Ubuntu 9.10 RC includes the 2.6.31-14.48 kernel based on 188.8.131.52. The kernel ships with Kernel Mode Setting enabled for Intel graphics (see below). linux-restricted-modules is deprecated in favour of DKMS packages.
Ubuntu 9.10 RC's underlying technology for power management, laptop hotkeys, and handling of storage devices and cameras maps has moved from "hal" (which is in the process of being deprecated) to "DeviceKit-power", "DeviceKit-disks" and "udev".
New Intel video driver architecture
The Intel video driver has switched from the "EXA" acceleration method to the new "UXA", solving major performance problems of Ubuntu 9.04. Ubuntu 9.10 RC also features kernel mode setting by default on Intel hardware, which reduces boot-time flickering and dramatically speeds up suspend/resume.
ext4 by default
The new "ext4" filesystem is used by default for new installations with Ubuntu 9.10 RC; of course, other filesystems are still available via the manual partitioner. Existing filesystems will not be upgraded.
If you have full backups and are confident, you can upgrade an existing ext3 filesystem to ext4 by following directions in the Ext4 Howto. (Note that the comments on that page at the time of writing about Ubuntu's use of vol_id vs. blkid are out of date and are not applicable to Ubuntu 9.10 RC.) Maximum performance will typically only be achieved on new filesystems, not on filesystems that have been upgraded from ext3.
GRUB 2 by default
GRUB 2 is the default boot loader for new installations with Ubuntu 9.10 RC, replacing the previous GRUB "Legacy" boot loader. Existing systems will not be upgraded to GRUB 2 at this time, as automatically reinstalling the boot loader is an inherently risky operation.
Some features are still missing relative to GRUB Legacy. Notable among these are lock/password support, an equivalent of grub-reboot, and Xen handling.
The iSCSI installation process has been improved, and no longer requires iscsi=true as a boot parameter; the installer will offer you the option of logging into iSCSI targets if there are no local disks, or you can select "Configure iSCSI" in the manual partitioner.
Putting the root filesystem on iSCSI is now supported.
AppArmor in Ubuntu 9.10 RC features an improved parser that uses cache files, greatly speeding up AppArmor initialisation on boot. AppArmor also now supports 'pux' which, when specified, means a process can transition to an existing profile if one exists or simply run unconfined if one does not.
Please see the AppArmor documentation for information on using AppArmor in Ubuntu.
In addition to the above changes to AppArmor itself, several profiles were added. Enforcing profiles for ntpd, evince, and libvirt are enabled by default. Complain mode profiles for Dovecot are now available in the apparmor-profiles package.
A new profile is provided for Firefox as well, though it is disabled by default. Users can enable AppArmor sandboxing of their browser by running:
$ sudo aa-enforce /etc/apparmor.d/usr.bin.firefox-3.5
This profile can be disabled again by performing:
$ sudo apparmor_parser -R /etc/apparmor.d/usr.bin.firefox-3.5 $ sudo ln -s /etc/apparmor.d/usr.bin.firefox-3.5 /etc/apparmor.d/disable/usr.bin.firefox-3.5
An AppArmor profile is now available for Apache in the libapache2-mod-apparmor package. When used in combination with the mod_apparmor Apache module, web applications can now be protected and isolated from each other. Instructions for enabling the profile are in the /etc/apparmor.d/usr.lib.apache2.mpm-prefork.apache2 file.
Please see the SecurityTeam/KnowledgeBase for a full listing of readily available profiles in Ubuntu.
Libvirt now contains AppArmor integration when using KVM or QEMU. Libvirtd is configured to launch virtual machines that are confined by uniquely restrictive AppArmor profiles. This feature significantly improves virtualisation in Ubuntu by providing user-space host protection as well as guest isolation.
The Uncomplicated Firewall now has support for filtering by interface and egress filtering when using the ufw command. Documentation for ufw is also improved to help users better utilise the ufw framework and take full advantage of Linux netfilter's power and flexibility. See UbuntuFirewall#Features for a full list of features.
Non-eXecutable (NX) memory protection, also known as eXecute-Disable (XD), has always been available in Ubuntu for any systems that had the hardware to support it and ran the 64-bit kernel or the 32-bit server kernel. The 32-bit PAE desktop kernel (linux-image-generic-pae) now also provides the PAE mode needed for hardware with the NX CPU feature.
For systems that lack NX hardware, the 32-bit kernels now provide an approximation of the NX CPU feature via software emulation that can help block many exploits an attacker might run from stack or heap memory.
Blocking Module Loading
To block the loading of any further modules after boot (generally for servers with unchanging hardware), the /proc/sys/kernel/modules_disabled one-way sysctl flag now exists to add another layer of protections against attackers loading kernel rootkits.
Building on the work done in Ubuntu 8.10 and 9.04 to proactively protect Ubuntu from unknown threats by using strict compiler flags, more applications have been built as Position-Independent Executables (PIE) to take advantage of the Address Space Layout Randomisation (ASLR) available in the Ubuntu kernel.
In addition to the growing program list, PIE programs are now also built with the BIND_NOW linker flag to take full advantage of the existing RELRO linker flag. This results in PIE programs having fewer places in their memory that can be controlled to redirect program flow when an attacker attempts memory-corruption exploits.
IBus replaces SCIM as preferred input method framework
Because SCIM is unmaintained upstream and has too many bugs which we can not fix, Ubuntu has switched to IBus as preferred input method framework. IBus is actively developed by Redhat employees and has fixed a number of design issues SCIM has.
Chinese language-packs, formerly containing both, Simplified Chinese and Traditional Chinese translations, have been split into two. This reduces the amount of data Chinese users need to download in order to get a localised system. Language-support-extra metapackages have been removed from the archive, they have been determined to be unnecessary and may lead users to download more stuff than they actually need in order to get a fully localised system. Language-support-translations metapackages have also been removed from the archive. Packages with additional translations, such as thunderbird or openoffice.org localisation packages are now installed by language-selector only if the main application package is already installed on the system. If a package gets installed for which there exist separate localisation packages, in Karmic it is still necessary to run language-selector manually to get the missing localisation packages installed. Language-selector now gives the user the possibility to select the preferred input method framework with a combobox.
There are a small number of known bugs that users may run into with Ubuntu 9.10 RC which will be fixed before the final release. We have documented them here for your convenience along with any known workarounds.
For a full list of errata for Ubuntu 9.10, please see the Ubuntu 9.10 release notes.
When creating LUKS encrypted partitions, some earlier versions of cryptsetup did not wipe out any pre-existing filesystem metadata on the partition. The current version of blkid used in the Ubuntu 9.10 RC will refuse to export a UUID for a partition containing more than one type of metadata signature. This means that encrypted disks may fail to be decrypted at boot time, possibly preventing the system from booting at all. Users of LUKS system-level disk encryption are advised to wait until the Ubuntu 9.10 final release before upgrading. (428435)
Empathy's MSN messaging support is provided by telepathy-butterfly, the version included in karmic advertises it supports Audio/Video chat however for stability reasons it has been disabled in Karmic. If you wish to test MSN AV support in Empathy, please install telepathy-butterfly from https://edge.launchpad.net/~telepathy/+archive/ppa and report bugs so we can make it as solid as possible in Lucid. (437828)
Installing on Marvell Dove boards requires a network connection. This will be fixed immediately after RC. (457536)
