Hi @J0WI
This PR breaks the upgrade process for me:

eaither updating from 34.0.0 to 34.0.1 or 34.0.2 throw this error.
I downgraded the PHP version by using php:8.4-apache-trixie as a base, and this error goes away.

I use the apache variant.

Have you set NEXTCLOUD_UPDATE?

@J0WI @ariaieboy I'am facing the exact same issue only with a bit larger version gap but it still happens:

According to your comment @J0WI I tried to set NEXTCLOUD_UPDATE=1 but the issue still occurrs with the exact same messages.
