today, i happened to be upgrading a different computer from 12.04 to 12.10, and am again seeing this same message [although it is now more difficult to diagnose since do-release-upgrade seems to now use screen].
what else can i do to help further troubleshoot this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1003411 Title: do-release-upgrade complains "WARNING: Failed to read mirror file" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1003411/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
