Problem
The open-xchange service is not starting successfully. You can't login to the service and commands like listuser are not working.
You can check this with service open-xchange status or by looking at the logfiles under /var/log/open-xchange/
In some recent support requests we found that the permissions in the osgi directory where wrong. If this is the case you see something like this in the open-xchange-osgi.log:
MESSAGE The -clean (osgi.clean) option was not successful. Unable to clean the storage area: /opt/open-xchange/osgi/org.eclipse.osgi !ENTRY org.eclipse.osgi !MESSAGE Error reading configuration: /opt/open-xchange/osgi/org.eclipse.osgi/.manager/.fileTableLock (Permission denied)
Root Cause
The open-xchange program should not be used to start the service as root user. Use the commands below instead. If you start open-xchange via this command it changes the permissions of some files/directories. Since 7.6.2 there is a check build in which will produce an error message and quit if you don't start it as the open-xchange user. Another cause could be wrong permissions from a backup or from copying files.
Solution
You have to change the permisions/ownership:
chown -R open-xchange:open-xchange /opt/open-xchange/osgi/
and restart the open-xchange service:
service open-xchange restart
or
systemctl restart open-xchange
