Someone pointed out to me that trac.common-lisp.net/cmucl is not working. That returns an internal error:
TracError: IOError: [Errno 13] Permission denied: u'/srv/project/cmucl/trac/log/trac.log'
I have no need for trac to be running, except for being able to see old tickets. No new tickets, updates to tickets, wiki changes or anything else is needed since everything has mostly been migrated to gitlab. Well except tickets.
trac seems to be available for other projects.
