I solved my own problem and it was a stale master lock. I deleted all files in the locks directory that begin with master.lck as follows: "rm /var/lib/mailman3/locks/master.lck*"

Actually, if Mailman core is not running, there should be no files in /var/lib/mailman3/locks/ and it is safe to remove any that exist.
