Upgrade Ubuntu 9.04 to Ubuntu 9.10 Karmic Beta
If you are looking to upgrade your Ubuntu 9.04 desktop or server distro to Ubuntu 9.10, this can be done with a few steps. To upgrade your Ubuntu desktop distro simply press Alt + F2 together. In the prompt box, type:
update-manager -d
If you have any problems, make sure that you have the update manager installed. To install the update manager, open up your terminal program and type in: sudo apt-get install update-manager-core To upgrade your server distro to the beta edition of Ubuntu 9.10; once again make sure that you have the update manager installed. Once the update manager is installed by typing in sudo apt-get install update-manager-core.
The next thing that you must do is edit /etc/update-manager/release-upgrades by typing vi /etc/update-manager/release-upgrades. Inside the/etc/update-manager/release-upgrades set Prompt to normal. Finally run sudo do-release-upgrade -d to upgrade your distribution.
Update: You can now upgrade your Ubuntu 9.10 Karmic to Ubuntu 10.04 Lucid Lynx Alpha 2 LTS by running the same commands specified above but instead of sudo do-release-upgrade -d run sudo do-release-upgrade –devel-release.
