Comment 3 for bug 1185077

Thank you for your report.

This looks like a local configuration problem, rather than a bug in Ubuntu, so I'm marking this bug as Invalid.

Specifically, it looks like you have a /etc/passwd.lock lockfile left over from a previous problem.

You can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

If you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug rather than a problem specific to your system, and then change the bug status back to New.
