I upgraded my Ubuntu 6.06 install to the new Edgy soon after it’s release using the simple command
gksu "update-manager -c". Several hours later, and after clicking on a few dialog boxes to update files in /etc/, I’m not running Ubuntu Edgy on my desktop box.
Initially I wondered where Firefox 2.0 was hiding, but on my upgraded system it’s /usb/bin/firefox.ubuntu so it’ll live alongside version 1.5. I also noticed that when saving files in the GIMP the filename would disappear when I clicked on a new folder in the “bookmark” folder of the Gnome file dialog. Once I noticed, ctrl-c to record the filename and ctrl-v to paste it in again worked fine. I rename my files when saving so it’s not much of a hardship.
My machine seems slightly faster but I haven’t delved too deeply into what has been upgraded but Firefox, xchat, terminal, GIMP and Gthumb all work fine! Did your upgrade go as well?
