Hi Karoliina! Thanks for your bugreport. Could you please run the following: $ update-manager -d
There should be a little button offering to upgrade to 7.04. Click on it and wait for the error. If it appears, please attach the files in /var/log/dist-upgrade/ to this bugreport. Thanks, MIchael ** This bug is no longer a duplicate of bug 79274 update-manager crashed in feisty ** Changed in: update-manager (Ubuntu) Status: Unconfirmed => Needs Info -- Update Manager's dist-upgrade to from Edgy to Feisty failed https://launchpad.net/bugs/79536 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
