| == System Requirements == ('''TODO:confirm with foundations and server teams this is still accurate - email sent 2012/03/12''') The minimum memory requirement for Ubuntu 12.04 is 384 MB of memory for Ubuntu Desktop. Note that some of your system's memory may be unavailable due to being used by the graphics card. If your computer has only the minimum amount of memory, the installation process will take longer than normal; however, it will complete successfully, and the system will perform adequately once installed. The minimum memory requirement for Ubuntu Server 12.04 is 128 MB of memory. The minimum memory requirement for Ubuntu Cloud 12.04 is .....??? '''TO DO''' Systems with less memory may be able to select "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop, or may be able to use the alternate install CD. = Upgrading = == Upgrading from Ubuntu 11.10 == === Desktop System === 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 display following message: "New distribution release '12.04' is available. Click Upgrade and follow the on-screen instructions". === Server System === To upgrade from Ubuntu 11.10 on a server system, follow the steps listed below: # Install the {{{update-manager-core}}} package (if it is not already installed). # Use following command {{{sudo do-release-upgrade -d}}} to launch the upgrade tool. # 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 dropped connection problems, for example. == Upgrading from Ubuntu 10.04 LTS to Ubuntu 12.04 LTS == '''TODO: Update from 8.04 --> 10.04 starting point, and with new changes.... ''' === Desktop System === To upgrade from 10.04 LTS on a desktop system, You can easily upgrade over the network with the following procedure. Start System/Administration/Software Sources On the Updates tab, set Show new distribution releases: to Long term support releases only, then press Close. Press Alt-F2 and type update-manager Click the Check button to check for new updates. If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete. A message will appear informing you of the availability of the new release. Click Upgrade. Follow the on-screen instructions. === Server System === Network Upgrade for Ubuntu Servers (Recommended) Ensure you're up to date with latest release: sudo apt-get update sudo apt-get upgrade Install update-manager-core if it is not already installed: sudo apt-get install update-manager-core edit /etc/update-manager/release-upgrades and set Prompt=lts Note: The minumum contents of /etc/update-manager/release-upgrades should be [DEFAULT] Prompt=lts Launch the upgrade tool: sudo do-release-upgrade Follow the on-screen instructions. At the end of the upgrade process you will be required to restart the server in order to boot into the new kernel. If you do not have access to the console of the system you are upgrading, you may need to edit /boot/grub/menu.lst and change the default boot kernel to the newly installed 10.04 kernel. If this step is not performed your server may attempt to boot into the 8.04 LTS kernel and will hang. == Upgrading from Other Releases == Users of other Ubuntu releases need to upgrade first to 11.10, and then to 12.04. For further information on upgrading to 11.10, please see the [[https://help.ubuntu.com/community/PreciseUpgrades| Precise upgrade instructions ]]. |
