Bug in Mailman version 2.1.26
We're sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs.
I was trying to log in to the mailman pending admin tasks page to delete an attempted post by a non-member.
in /var/log/mailman/error is:
admin(22004): [----- Traceback ------]

I don't know what to do about this.

Lockfile.__write is a nearly trivial function; I doubt this is a bug, rather a configuration issue or an environment it's not designed to work in.
It appears this process is running as www-data. Does /var/lib/mailman/locks exist? Is it a directory? Is it readable and writable as a directory by www-data or www-data's group? Is it on a local disk, or some kind of network file system?
SCRIPT_NAME: /virtualmin-mailman/unauthenticated/admindb.cgi
This is not provided by Mailman, I suspect, unless it's a link to a Mailman script. What does it do? Is it just a call to /var/lib/mailman/scripts/driver?

Actually, the owner of /var/lib/mailman/locks doesn't matter. The key requirement is its group is Mailman's group ('mailman', 'list', whatever Mailman runs as)

This is probably the standard CGI wrapper for admindb. It too should be Mailman's group and SETGID.
Does the admin URL have the same error?
