welcome to Univention Help
With the current state of your post, it will be hard for other users to provide help. We encourage you to have a look at our Posting Guidelines and update your post accordingly.
- I moved your post to the correct category (UCS - Univention Corporate Server)
- Please provide the UCS version and the installed components (copy the output of
univention-app info and paste it here)
- What was the UCS version before the update?
- Bonus points for a screenshot of the error message
That being said, I'd start the troubleshooting with the steps described here: http://sdb.univention.de/1271
Enjoy your stay at Univention Help
