I'm running Ubuntu 12.04/AMD64 .... actually Linux Mint 13/Mate.... and after a recent update that included 162 updates I get a report of "broken package" on libgl1-mesa-glx.

I have no idea what to do about it.

I've tried a number of generic suggestions like apt-get -f install and similar but nothing works.

I've thought about using synaptic to remove it and then re-install it but I don't know how vital it is and I don't want to wind up with an unusable system.

Suggestions?
