I'm getting the same error when trying to back up an existing 2022.12 instance:

Info: Backing up the MySQL database... Warnung: mysqldump: Error 1412: Table definition has changed, please retry transaction when dumping tableworkerqueueat row: 0

What can I do?

[sekretaerbaer]

connect to the server via ssh and with sudo su become root then change to the directory /var/www/friendica and execute the command bin/console maintenance 1 . The command puts the Friendica in maintenance mode and stops the database.

then you should be able to make a backup via the web interface as usual.

Is the backup created Friendica again with the command bin/console maintenance 0 from the maintenance mode back.
