Comment 5 for bug 342778

Thanks for the steps to reproduce. This error appears when you try to sign a key not in your keyring yet, you have to import it first. The issue has been fixed, mostly by not displaying non-available actions.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest version of Ubuntu - the Jaunty Jackalope.

If you need a fix for the bug in previous versions of Ubuntu, please follow the instructions for "How to request new packages" at https://help.ubuntu.com/community/UbuntuBackports#request-new-packages
