Something is broken in MxLinux and I’m not sure if an update broke it or my attempt to configure it to work with guacamole.  There are too many variables to troubleshoot each individually.  I am going to restore it from backup.  There will be a short downtime while it reboots from a backed up image. If it works properly I will then re-apply the updates and see if it still works.  If so I’ll again attempt to configure it to work with guacamole.
