Comment 7 for bug 624229

I also have this problem, but it affects Lucid (10.04) and Maveric (10.10). However, I don't have a flashdrive or anything else but an ext4 system drive in a notebook.

Also there are no messages in my /var/log/messages that pertain to apt, dpkg or the like.

It would be nice to learn how to debug this in more detail. Can anyone help?
