After upgrade, I can reproduce this bug if I try to install fsharp-console directly, but if I install mono-gac and THEN install fsharp-console everything dies.

repro:

sudo apt-get purge mono-gac
sudo apt-get install fsharp-console

workaround:

sudo apt-get purge mono-gac
sudo apt-get install mono-gac
sudo apt-mark auto mono-gac
sudo apt-get install fsharp-console

Status changed to 'Confirmed' because the bug affects multiple users.

Medium: Package won't install
Although it looks like a dependency problem from the workaround.
