Vaultwarden fails to start after update – DB migration error (SSO)

[apesorguk]

Thanks all fixed now. I found this worked even with the line brake.

I have run the command sed -i 's/\r$//g' /app/data/fix_db.sh to fix the new line characters and then run bash /app/data/fix_db.sh again and it ran as expected. Disabled recover mode and confirmed things are back to working as expected.

Vaultwarden not responding. Backup restore from December 29th, 2025 works. No backups after that are working. There is nothing in the Cloudron logs that show any error. There was only an update on Dec 31st that appears to be the start of the problem.

I used this issue to improve my aidevops cloudron subagent, and it managed to fix the issue on all instances. More info here for anyone interested to add this to your toolkit:
