Comment 0 for bug 427035

update-manager hang during a dkms module installation because tmp was full. that was caused by a full / (root-) directory so that tmp had been mounted on overflow (as here: https://answers.launchpad.net/ubuntu/+question/34535). When I had started the distribution upgrade I made sure there was enough space on /. I did not check /tmp however (which ist normally on the same partition as /). update-manager should recognize this situation and not start a distribution upgrade when /tmp is mounted on overflow. this happened during an upgrade from jaunty to karmic.
