I did update Nextcloud on TrueNAS 24.04.02, which broke the app. I then found out that I need to change the postgres version to 17, but this option is only visible in EE (TrueNAS 24.10). So I did update TrueNAS to 24.10, changed the Postgres to 17, Nextcloud, after a long time, manage to run but is stuck in maintenance et request an update. The DB migration was done apparently, it’s now on 17. I have also migrate the user data to the separate folder as recommanded.
But now I cannot use Nextcloud because by doing all of this I skipped 2 nextcloud versions I guess. So doing the upgrade in occ give me this error:
Exception: Updates between multiple major versions and downgrades are unsupported.
I tried to boot back to 24.04 but Nextcloud fail to start there, I guess because of the DB migration and user data migration.
Any idea how I can save the situation?
