Public bug reported: used recomended command gksu "update-manager -c" typed in password chose the upgrade option beside the Ubuntu 6.10 in the popup window upgrade starts and completes the first two steps (which names I don't remember) giving an error that it can't change sources.lst and on the third step prints this error and rolles back to Dapper
"A unresolvable problem occurred while calculating the upgrade. Please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bugreport." so here are the suggested files contents: ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- Error during Upgrade to Edgy https://launchpad.net/bugs/93455 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
