Comment 2 for bug 281058

I confirm that rarian-compat fails to get installed during the upgrade process. However, by removing rarian-compat package and installing scrollkeeper instead (the seem to be interchangeable) I was able to finish the upgrade process and get the working installation if Intrepid. The problem is, ubuntu-desktop depends on rarian-compat and refuses to have scrollkeeper instead, so one has to watch out: removing ubuntu-desktop during upgrade can blow the system completely.

Once the upgrade process is finished, rarian-compat (and ubuntu-desktop) can be installed without any problems.
