It effects me as well with Ubuntu 9.04. The Update Manager offers me [Partial Upgrade]. I click it, wait for the downloading to finish, and get a screen that offers me to [Start Upgrade]. I click it and immediately receive this error message.
I tried to run the Update-Manager as root but got the same error. A [Retry] button would be good, allowing me to try and remove this lock before the Update Manager starts to undo all changes. Is there a work-around? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/224539 Title: Failed to lock /var/cache/apt/archives/lock -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
