"subprocess post-installation script killed by signal (Interrupt)" in configuring mono-gac looks like you pressed ctrl+c or something while this was running. As mono-gac was not correctly configured many other mono apps couldn't be configured.
Can you reproduce this somehow? ** Changed in: mono (Ubuntu) Status: Unconfirmed => Needs Info -- mono-gac postinst fails on dapper->edgy upgrade https://launchpad.net/bugs/67379 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
