Exception: Updates between multiple major versions and downgrades are unsupported. Error maybe in Database

luismauriz1 · November 10, 2023, 6:03pm

Hello,
i have problems with my Nextcloud Installation.
My Nextcloud is running in a NCP Docker container.
It seems that my Updater Skipped some Nextcloud versions while updating. Now i get the Command as you see above.
I tried removing the version string completly from the config file.
also a clean reinstall of the container and loading in the mysql file werent working. so for me it seems that the version string is inside the mysql database and the occ upgrade is because of this not possible.
I know this is not the Support Template but In my view the logs are not a elp
Thanks for your help!

Let someone else view the logs. Share output of ncp-report,
If not, I’d suggest a a fresh install.

Adding feasibility check for updates before replacing the nextcloud files

I'm creating this issue to collect all the other issues related to broken update…s that try to skip a major release. Nextcloud does not support skipping a major release while updating. So going from `13->15` will not work without including version 14: `13->14->15.` The problem is, that the entrypoint script correctly detects that the image version is greater, but does not check if the upgrade is feasible. So it overwrites the Nextcloud files (including `version.php`) and does not fail until running the occ upgrade command `run_as 'php /var/www/html/occ upgrade'`. Upgrading fails and the container exits, but the user can't go back to his initial state because the Nextcloud source files are already replaced. He also can't trigger a proper update from `13->14` because the upgrade detection is broken (`version.php` now falsely claims version 15). #597 in my opinion does not enough, but is a good start to at least document that Nextcloud might break when updating. However a check should be introduced to protect the Nextcloud install in that case. I think it is no problem, that running the new containers fails, but the Nextcloud instance should be unharmed. related issues: #616 #605 #585 #722

In nextcloudpi you can set the version to update to. So if you are on 25, put in the latest 25.x.y and update to it. The the latest 26.x.y and update to it.

NCP docker images are outdated as it seems. Maybe it’s the right time to switch to nextcloud AIO https://github.com/nextcloud/all-in-one
