why debian 9 `? Shouldnt it run on other distros too ? Just asking because im too lazy to test on my ubuntu 21.04 server :
Any informations about requirements like minimum CPU and RAM ? Could a G2030 with 16 GB ram be enough for a decent server ?
You can setup the server on most distributions. For a long time all tutorials used an old Centos version. Debian 9 is used for most tutorials now because of the installer, we wrote it with Debian 9 in mind.
Last time I checked, Ubuntu worked fine - but that was years ago. Since Ubuntu is Debian based you can try to use the installer and hope for the best.
Unless you want to host a public server, you don't need a mid to high end server to have a good experience. The files run pretty well on low end servers, just make sure to get at least 2 cores and about 4GB RAM (of course more is always better).
