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/lubuntu/releases/precise/alpha-1/ (Lubuntu) <<BR>> http://cdimage.ubuntu.com/mythbuntu/releases/precise/alpha-1/ (Mythbuntu) <<BR>> ## Not releasing Alpha1 images ## http://cdimage.ubuntu.com/ubuntustudio/releases/precise/alpha-1/ (Ubuntu Studio) <<BR>> = New features in Precise = 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 ## already mentioned directly below ##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 3.2.0-2.5 Ubuntu kernel which is based on the latest mainline [[http://kernel.org/|v3.2-rc3 release candidate kernel]]. This is an update from the v3.0 kernel in Oneiric. Some additional highlights include: * Consolidated amd64 server flavour into generic * armhf — enable armhf and create the first flavours * Support for additional ALPS touchpads * Updated seccomp patch set * Set CONFIG_PANEL_DVI=y on arm * Enable CONFIG_EXT2_FS=m * Build in CONFIG_SATA_AHCI=y * Built-in xen-netfront and xen-blkfront * Allow brcmsmac and b43 to both build == 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 == ## Not releasing in Alpha 1 == 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: == Boot, installation and post-install == * Sometimes the installer crashes in the middle of copying files to the target system. This mostly seems to happen with installation in virtual machines such as KVM, VMWare, or VirtualBox, but it has been observed on real hardware as well. The workaround is to just re-attempt the installation. (Bug:894768) * On the pre-installed ARM images, sometimes the installer packages are not removed after first-boot setup, which will cause the first-boot setup to be re-run after next boot. The workaround is to manually remove the packages `ubiquity oem-config oem-config-gtk jasper`. (Bug:871785) * There is no network support on some Beagle board versions. (Bug:838200) == Graphics and Display == == Desktop == * The background image of the login greeter still says "Ubuntu 11.10". (Bug:892394) == 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.
