The issue you are facing:
Hi everyone,
After putting NC to maintenance mode off (true) and swichting back on (false), NC wants to run the web-based upgrader (or ./occ upgrade);
Running the web-based upgrade returns this error message.
Ist there a way to disable the upgrade? What is the issue? As far as I am aware, I have the current version.
Thanks.
Error Message:
Nextcloud or one of the apps require upgrade
Exception: Updates between multiple major versions and downgrades are unsupported.

I am running NC on shared hoster (all-inkl), and only access to ssh!
Running occ maintenance:repair return the same message to upgrade.
Is this the first time you’ve seen this error? (Y/N): Y
