Before the update the log is cluttered (26 MB) with these lines. They are there after the update plus messages that other users cannot connect.

not sure where to find additional information

Can I undo this update? A backup was created but know I read that I also had to do database backup. Was not aware that I need to do this manually.

There is no admin folder other than the Admin users folder. There is in the root of /data, a file called nextcloud.log

I updated my post with the log.

You got doubleslash between lib and AppInfo.
