I’m new here, and if this has been addressed, I couldn’t find it. Anyway, I installed the 64-bit Deb version, and it installed fine, ditto for clang and git. I was able to edit my program (Marlin v.2.0 for 32-bit 3d printers), and upload it to the board with no problem. The issue is that when I exit Atom, and try to restart it later, it just repeatedly crashes. The only fix is a complete purge including the .atom folder, and reinstall.
