Comment 5 for bug 67368

Unfortunately it's not. I've already completed the upgrade.

I think the problem was caused by some package that could not be downloaded (look at the end of main.log), which in turn broke the transaction that the update-manager had precalculated.

I started it again, it downloaded a few more packages (which seems to confirm my idea), and then it crashed again, because for some unknown reason the initscript for "lighttpd" returned exit status 1 when the pre-removal script run it. That's because for some reason the /etc/init.d/lighttpd script returned 1 trying to stop the service.

At that point, I decided to gave up on update-manager and get my hands dirty. I edited /etc/init.d/lighttpd, and added an "exit 0" as the first line. After that, and a few aptitude update, aptitude dist-upgrade and aptitude -f install, I finished the upgrade.

So, to sum it up:
 - it seems that update-manager doesn't get notified if a package can not be downloaded (this I think is a bug)
 - maybe there's a bug in the lighttpd pre-removal script; or smething broke in between (lighttpd was starting/stopping normally before the update), but the fact is that update-manager could not deal with it (and I think that's a pitty but it's fine... a pre-removal script can fail for a thousand reasons, and could not be ignored that easy.)

Here's the last lines of my last attempt with update-manager:
