Just encountered it again. UM had notified that Thunderbird updates were available, but I decided I didn't want Thunderbird anymore. I closed UM and started Synaptic, found Thunderbird and marked it for removal, hit apply, and was told the lock file was there.
My system is fully up to date, including update-manager 1:0.111.9. Any other information that would be useful?.. ** Changed in: update-manager (Ubuntu) Status: Incomplete => New -- [jaunty] update manager lock file not always removed https://bugs.launchpad.net/bugs/124387 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
