I did an upgrade from 7.10 to 8.04 two nights ago. Everything seemed to be fine, until I opened Network Manager...then all hell broke loose. It gave me a hard time setting up my network, because sudo commands don't work. For some reason, the upgrade renamed me to some dotster.com nonsense, and using gedit is not an option to fix the problem. I've also tried to Hotwire it, but it ignores me in the booting sequence, so that's out. I was pretty excited about this upgrade, and it fixed a lot of issues I had with 7.10 but in end, not being able to root in, is kicking my ass. I'm locked out as a normal user, and root is now in the hands of the laptop and the Ubuntu program. Any ideas on how I can circumvent this problem?
