Seems to work for me. I rebooted. I can mount my Windows partition. I can browse the internal Windows network. Nothing seems broken. Some backstory: I discovered this bug when trying to solve my own "askubuntu.com" problem, see: http://askubuntu.com/questions/128933/cannot-update-nfs-the-update-manager-shows-packages-but-wont-let-me-select-the In the above URL, I am using the "Update Manager" GUI. When trying to help solve this bug (eg. a reply to comment #7 by cjwatson) I did 6 steps: 1) I went into the graphical "Ubutnu Software Centre" 2) I put a checkmark next to "precise-proposed" in the Sources tab; Edit -> Software Sources. 3) In "Update Manager" i clicked "Check." At this point I was asked to upgrade something like 90+ packages. I freaked out a bit and exited the GUI. Instead, I went to the terminal and I did 4) -=-=- $ sudo apt-get install rpcbind nfs-common Reading package lists... Done Building dependency tree Reading state information...
