I do not really understand the background of this question. The original text was posted as question 151811 by Mark Hopkins on 2011-04-06 and marked as solved by him on 2011-04-07 (root cause apparently errors in proxy definition).
Now, two and a half years later, this is posted as new bug by reema. By the way, meanwhile karmic is really in "End of life" status, and the repositories have been offloaded to old-releases.ubuntu.com Taking all that into account, in my opinion this bug report should be closed as invalid. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242282 Title: no suitable download server was found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1242282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
