Update from 11.0.3 to 11.0.4 failed

Nextcloud version 11.0.3:
Operating system and version Debian 8 Jessie:
Apache or nginx version Apache/2.4.10:
PHP version PHP 5.6.30:
Is this the first time you’ve seen this error?: yes

Can you reliably replicate it? (If so, please outline steps):

I used the webupdater in order to update from 11.0.3 to 11.0.4. Have updated this way many times before.

The issue you are facing:
Nextcloud 11.0.3 told me that there is an update 11.0.4

I started the update and got an exception:

Exception: Updates between multiple major versions and downgrades are unsupported.

I am not aware that I updated between major versions or downgraded something.

The output of your Nextcloud log in Admin > Logging:

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

Where you able to solve the problem? If yes, then how?

I’m stuck with the same error message also on debian jessie with sqlite.

Unfortunately not. I had to reinstall Nextcloud.
