As Ubuntu UI is more and more annoying i decided to try linux mint.
Here is a short howto how to switch from ubuntu oneiric to current mint.
Add the following to sources.list:
deb http://packages.linuxmint.com/ lisa main upstream import
sudo apt-get install linuxmint-keyring
This installs the key, so future update go as usual (beware, this way you trust linux mint!).
sudo apt-get install mint-meta-mgse
