The Precise Pangolin Alpha 1 Release of Ubuntu 12.04 is a '''developer snapshot''' to give you a very early glance at the next version of Ubuntu. = Get Ubuntu 12.04 = == Upgrading from Ubuntu 11.10 == To upgrade from Ubuntu 11.10 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 '12.04' is available. Click Upgrade and follow the on-screen instructions. To upgrade from Ubuntu 11.10 on a server system: install the {{{update-manager-core}}} package if it is not already installed; launch the upgrade tool with the command {{{sudo do-release-upgrade -d}}}; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems. == Download the Alpha 1 == This release is for '''developers only'''. Most of these images are oversize; you can use either a DVD or USB for installation instead of a CD. You can download Alpha 1 ISOs from: http://cdimage.ubuntu.com/releases/precise/alpha-1/ (Ubuntu Desktop and Server) <<BR>> http://uec-images.ubuntu.com/releases/precise/alpha-1/ (Ubuntu Cloud Server) <<BR>> http://cdimage.ubuntu.com/kubuntu/releases/precise/alpha-1/ (Kubuntu) <<BR>> http://cdimage.ubuntu.com/xubuntu/releases/precise/alpha-1/ (Xubuntu) <<BR>> http://cdimage.ubuntu.com/edubuntu/releases/precise/alpha-1/ (Edubuntu DVD) <<BR>>. http://cdimage.ubuntu.com/ubuntustudio/releases/precise/alpha-1/ (Ubuntu Studio) <<BR>> http://cdimage.ubuntu.com/lubuntu/releases/precise/alpha-1/ (Lubuntu) <<BR>> http://cdimage.ubuntu.com/mythbuntu/releases/precise/alpha-1/ (Mythbuntu) <<BR>> = New features in Oneiric = Please see the [[https://blueprints.launchpad.net/ubuntu/precise/+specs|Precise blueprint list]] for details. Please test and report any bugs you find: http://help.ubuntu.com/community/ReportingBugs == Updated Packages == As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from [[http://www.debian.org|Debian's]] Unstable branch, others have been explicitly pulled in for 12.04 Precise Pangolin. For a list of all packages being accepted for 12.04 Precise Pangolin, please subscribe to precise-changes: https://lists.ubuntu.com/mailman/listinfo/precise-changes Some of the key packages making their first appearance with this Alpha 1 release are: * [[http://kernel.org|Linux]] Kernel 3.2-rc3 * ? === Linux kernel 3.2 === Alpha 1 includes the 3.2-rc3 kernel which is based on the latest mainline release candidate kernel at kernel milestone freeze [[http://kernel.org|kernel]]. This is an update from the v3.0 kernel in Oneiric. == General == Until Ubuntu 11.10, the Unix group for administrators with `root` privileges through sudo had been `admin`. Starting with Ubuntu 12.04 LTS, it is now `sudo`, for compatibility with Debian and sudo itself. However, for backwards compatibility, `admin` group members are still recognized as administrators. Automatic Apport crash reporting has been enabled by default again to catch problems early on. It now [[http://www.piware.de/2011/11/apport-1-90-client-side-duplicate-checking/|checks for duplicates on the client side]], which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now. == Ubuntu == The default music player has been [[UbuntuSpec:desktop-p-default-apps|switched to Rhythmbox]]. There is no UbuntuOne Music Store yet, this still needs to be ported to GTK 3. == Ubuntu ARM == TO DO: ?? == Ubuntu Server == TO DO: ?? == Ubuntu Server Cloud images == There are no significant changes for Alpha1. == Kubuntu == TO DO: ??? == Xubuntu == TO DO: ??? == Edubuntu == TO DO: ??? == Lubuntu == TO DO: ??? == Ubuntu Studio == TO DO: ??? == Mythbuntu == TO DO: ??? = Known issues = As is to be expected, at this '''very early''' stage of the release process, there are some significant known bugs that users may run into with the Oneiric Alpha 1 Release. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again: == Graphics and Display == == Desktop == == Boot, installation and post-install == == Migration == == Kernel == == Software Center == == Ubuntu Server == == Ubuntu Cloud == == Kubuntu == == Edubuntu == == Xubuntu == == Lubuntu == == Ubuntu Studio == == Mythbuntu == '''For a listing of more known issues, please refer to the Precise Pangolin [[https://bugs.launchpad.net/ubuntu/precise/+bugs|bug tracker]] in Launchpad.''' = Reporting bugs = It should come as no surprise that this Alpha 1 release of Precise Pangolin contains other bugs. Your comments, bug reports, patches and suggestions will help fix bugs and improve the quality of future releases. Please [[http://help.ubuntu.com/community/ReportingBugs|report bugs using the tools provided]]. If you want to help out with bugs, the [[http://wiki.ubuntu.com/BugSquad|Bug Squad]] is always looking for help. = Participate in Ubuntu = If you would like to help shape Ubuntu, take a look at the list of ways you can participate at http://www.ubuntu.com/community/participate/ = More information = You can find out more about Ubuntu on the [[http://www.ubuntu.com|Ubuntu website]] and [[http://wiki.ubuntu.com|Ubuntu wiki]].
