@StarshipKnight That's a generic error message when the compilation (and the follow-up installation) fails. You'll find the detailed error message in the ~/RetroPie-Setup/logs folder, in the most recent log file.

@etheling said in Retropie Installation on Ubuntu Server x64 18.04.1:

That makes total sense. I have a PXE boot setup at home through which I can (most of the time ;-) automatically image my dedicated RetroPie NUC, etc. so it fits my setup very well. Main benefit I see is that it provides a sort of stable starting point for these other scripts that tune the Ubuntu based RetroPie setup.

I do exactly the same, using a combo of pfsense/unRAID for all of the heavy lifting.
