Nextcloud informed me: V18 is no longer supported, so I set about upgrading it.
NC is running in a docker container. Looking on the internet I found what to do:
docker-compose down
docker-compose pull
docker-compose up -d
(Some of you may already scream at the screen…)
Everything looked good, but NC was now in maintenance mode, some more looking around:
docker exec -u www-data -it nextcloud-app /bin/bash
php /var/www/nextcloud/occ maintenance:mode --off
did not work, occ was in /html … same command with new location → worked.
Now I could click the upgrade button, but … then it said I cannot upgrade over multiple major versions …
So I tried the following in my yml-file:
image: nextcloud:19
Well now NC won’t start because: Data is version 22.1.1.2
What to do now?
