Public bug reported: A few days ago, while installing automatic updated (in the "background" while doing other stuff, so I didn't know it was because of the updates), the whole system froze, that is, stopped responding to mouse, keyboard and anything. Not even Ctrl+Alt+F1 would work, so the only thing I could do was a hard power off.
I rebooted and I thought that had been something sporadical, but now I wanted to install some package, namely yasm, so I did: $ sudo apt-get install yasm and the output was: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. I ran 'sudo dpkg --configure -a' There were a few scary lines in the output regarding grub and linux images (as if it was reinstalling and/or reconfiguring grub for some reason), including: killed done Then after some more lines like "Processing triggers for whatever" it repeated the stuff about grub. It got stuck for several minutes after a message that read something like "Windows loader found at /what/ever" (got stuck meaning it would neither produce any more output nor would it exit to the command line), without consuming any significant amount of cpu. Some minutes later, Chrome would only display blank pages, and while I was clicking on Google Chrome's window's button to close it, the whole system stopped responding again, forcing me once more to power it down the "hardware" way. I repeated the whole process once more. So: dpkg is broken, MY WHOLE SYSTEM IS BROKEN and I can't install any packages or system updates.
