I cannot update NFS. Ever since I upgraded from 10.04 LTS the update manager shows two NFS packages but it won't let me click them.

Update Manager NFS Problem

What should I do?

I tried:

sudo apt-get -oDebug::PkgProblemResolver=1 dist-upgrade

But It didn't help, eg:

Reading package lists... Done

I found a bug report similar to my problem, but I don't understand how I can "bump the priority of rpcbind in the archive to 'standard?" What does this mean? Can anyone point me in the right direction?
