I've run into the same problem, also hanging in mlock. I'm trying to upgrade to Karmic...
I ran gpg --verbose --debug-all --status-fd 1 --list-packets --no-default- keyring --ignore-time-conflict --keyring /etc/apt/trusted.gpg --verify /tmp/tmpF3xNHa/karmic.tar.gz.gpg /tmp/tmpF3xNHa/karmic.tar.gz which is the command that update-manager tries to run with debugging added. No output is produced.
