update-manager -d fails to run blabling something about "ubuntu-minimal"

[Martín Cigorraga]

What an smooth upgrade!
Wait... no, it isn't O_o
In fact the updater fails leaving me stranded, good job there! Well, after all it isn't unusual to end up with empty hands and the system breaked after upgrading Ubuntu, seems nothing changed from when I stopped using the distro back at the 7.04 release, lol!!! Good job and two -ironic- thumbs up gentlemen!

Awesome! Just found is a long-standing bug that was never been addressed - good job! (er, really not)
Btw, I already marked it duplicate.
