Hi Lee, thank you for taking the time to file this bug report and help us make Ubuntu better.
You seem to have a file on the system that is interfering with the success of the post install script. Notice here: Setting up courier-base (0.63.0-2.1ubuntu1) ... update-alternatives: using /usr/bin/deliverquota.courier to provide /usr/bin/deliverquota (deliverquota) in auto mode. update-alternatives: error: alternative link /usr/share/man/man5/maildir.5.gz is already managed by maildir.5. dpkg: error processing courier-base (--configure): subprocess installed post-installation script returned error exit status 2 This is failing on this command: update-alternatives --install /usr/share/man/man5/maildir.5.gz maildir.5.gz /usr/share/man/man5/maildir.courier.5.gz 5 Please run update-alternatives --list maildir.5 and dpkg -S `update-alternatives --list maildir.5` And paste them here. The second command, btw, should list the package that owns the link in error. Marking Incomplete pending response from Lee. ** Changed in: courier (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709557 Title: package courier-base 0.63.0-2.1ubuntu1 failed to install/upgrade: -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
