I don't see ubuntu "at fault" per se. But the error message could have been more meaningful. The whole handling could (!) have been smoother.
BTW, what was bad about the sources.list file? I just thought it was redundant but I did not think it was broken per se. Did it violate the specs? In that case it would be fairly easy to set up a test for "broken sources.list" syntax and improve handling of these kind of situations. -- Error while updrading from Dapper to Edgy https://launchpad.net/bugs/68849 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
