So I've been putting off doing updates and upgrades for AGES, and plus because I don't want unity and like having the window list not grouped at the bottom and having the character palette at the top 'cause I have to write with foreign Characters quite often so it's handy but I finally went to do a partial upgrade today, as suggested by the update manager, and I've left it to do its stuff but it's been stuck on: Unpacking replacement libc-bin ... for over 3 hours now.
aWhat can I do to push it along, or what could be stopping it from progressing?

If you still hang: Abort and go to a shell:
and then
I made the experience without understanding why, that it often works that way. In theory it should be the same.
