A bit of a sidenote and definitely an unpopular opinion coming up… The nextcloud snap is perhaps the easiest and among the most stable ways to run NC. And I base this on my own experience, having installed and tested NC on numerous devices in several ways. You loose some tinkerability and the performance is nothing to write home about. And yes I know - snap no good - Canonical evil. That having been said, If stability and easy setup is what you want, it’s worth considering.
