This happened to me, hence finding this post. I had started an upgrade then my pc had been turned off.

Fixed it with

apt-get -f install

Seemed that libc6 wanted to ask if it was OK to stop services to continue - I was upgrading headless using screen. The upgrade didn't get an answer to that question thus libc6 wasn't installed.

Carrying on the do-release-upgrade now.
