We test NoMachine with many flavours of Linux, there are hundreds out there, unfortunately we can’t test with all of them 🙂
The main reason is that Alpine Linux is shipped with musl instead of glibc. We are trying to figure out if there are more problems with it and checking if it’s possible to run NoMachine on Alpine at this time
Also we will need some additional information. Please collect /usr/NX/var/log/nxinstall.log and /usr/NX/var/log/nxupdate.log (if it exist) files, send those information to forum[at]nomachine[dot]com, please.
