Comment 15 for bug 27636

Unfortunately I can not do that, because I did not do a "dist-upgrade". update-manager told me that a dist-upgrade would be impossible, which - AFAIR - was related to the fact that I had no "ubuntu-desktop" package installed (probably because I got rid of some unneeded packages which are a dependency for the desktop package somewhen in the past).
So, all I did was manually changing my sources.list and apt prefs to edgy and then tell synaptic to update everything. I did that two or three times until nothing updatable was found anymore.
The only package I have NOT updated to latest edgy yet is "ubuntu-minimal" (held at version 0.120) because I was afraid that upstart could break my custom boot setup. So I postponed this package update for further analysis.

So I had - as written above - an "update", not an "upgrade". Which means, that all I have in /var/log/dist-upgrade is a file that will explain to you why my dist-upgrade failed. If you want that I can mail it to you.
