I installed Collaboration Server 1.2.1 on Ubuntu 20.04 successfully.
However, I get a 500 error after a user, team, or group creation command.

The error message indicates that access to the database is read-only.

extract of the error message:
Caused by: java.sql.SQLException: An SQL data change is not permitted for a read-only connection, user or database.

How to check the database access rights?
How to change access rights?

Thank you for your help.

Best answer

For users wanting to set it up with tomcat9:

Tomcat9 is sandboxed and has no access to the filesystem, to enable access to /opt/collab you need to create a file /etc/systemd/system/tomcat9.service.d/override.conf containing:



and then run

systemctl daemon-reload

systemctl restart tomcat9

The tomcat user must own the collaboration server directory (e.g. /opt/collab) and all its child directories. Maybe that is the issue?

Meanwhile I also had this issue with tomcat9, there is a change in tomcat, it is now sandboxed and has no default access to the filesystem. I will create an updated documentation for tomcat9
