Yesterday I attempted to upgrade my server from Ubuntu 6.06 (dapper) to 6.10 (edgy eft) with disastrous results. The upgrade was incomplete & after it finished X11 wouldn’t start. I booted up in recovery mode and completed the install and was able to start X11 and have most things working. Unfortunately it got worse from there. When I rebooted it would always freeze when checking devices. It turns out my boot drive was bad.
Luckily I had a spare drive so I was able to replace it. I did a clean install from a Dapper CD and I’m now in the process of upgrading to Edgy before I install anything else. That will take a few hours.
