I have already tried to recover with borgbackup from the last six days.

I have no clear indication when these problems started. But, we have had a total outage of external network connection just before I recognized these problems. As a result of this outage I have received a new IP address.

last attempt was:

$ sudo docker stop nextcloud-aio-database
$ sudo docker rm nextcloud-aio-database;
$ sudo docker image prune -af

followed with restore from borgbackup in AIO-webinterface in port 8080 and then update of all containers.

No progress in database container:

pg_ctl: server does not shut down
The database import failed. Please restore a backup and try again.
For further clues on what went wrong, look at the logs above.

source of the message is probably database restore in start.sh of postgresql.
Please provide a hint how to recover my system.
