Comment 53 for bug 811441

Similar problem here, fixed using the above procedures.

/run existed, had some content
/lock existed, empty
/var/run had content, a directory vmblock-fuse couldn't be deleted until unmounted

I also noticed a crash dump during the upgrade, while attempting to close the wireless interface. My wireless interface was switched off (hardware switch) at the time, I was using wired ethernet.

Wireless and wired working fine after the fixes above. 3G dongle also looks ok (poor signal here, hard to be sure).
