Can't build on Neon

This is less of a question and more of a bug report (though I guess a more relevant question is where the hell do I report bugs for the linux version)

Downloaded the most recent version from github today - which is 4.12. I tried to make it on KDE Neon, but make fails. The issue is in os-release - Neon uses two id_like parameters - debian and ubuntu. The space between the two trips up the make script. temporarily deleting “debian” from the end fixes the issue.

I suppose the best question is “how do I report this as an actual bug?”
