If you want support, you will have to use a version of PHP compatible with the version of NC.
And when you “fool the system” and it’s completely dysfunctional, then what? I suppose you will want the community to address that too. I think you won’t find a lot of people willing to volunteer their personal free time on a system intentionally set up incorrectly.
I was just trying to provide a viable upgrade path.
This was my approach:
installed a fresh rasbian (Bullseys , debian 11) from 22 september 2022 . 64 bit.
Then installed NCP version v1.48.3 which installed mariaDB 10.5 , PHP7.4 , Apache2 (2.4.54-1) and Nextcloud 23.0.6 and obviously a lot of other stuff.
How would an NCP upgrade path look like taking care of all the layers that are in between?
