after hours I tried to change distribution and went with fedora, set up everything, installed immich, not a single problem, it all works, also duckdns, and now I also have btrfs so I can snapshot my system. I’m probably very unlucky with debian based distributions, on my main laptop I had many problems with ubuntu as first distro, I had to distro hop a bit to find my place in EndeavourOS
thank you very very very very much for your time and help, I really appreciate this! now it’s time to actually start this journey in the magic world of self-hosting!
