Just updated my Seafile cloud server to version 12.0.10. Even though running it with Docker, it’s always a bit of a gamble if it works quite fine.
Had to adjust different configurations, check the logs (via docker-compose logs -f) to see that my external MySQL 8 server doesn’t seem to be supported anymore, since I had to adjust some migration SQL queries to remove the IF NOT EXISTS from statements like ADD COLUMN.
In the end, it eventually worked, though. 🙂
