Did the following: 1. install the latest daily build of artful (http://cdimage.ubuntu.com/daily-live/current/artful-desktop-amd64.iso) 26-sept 2. Install the latest mainline 4.14 from here linux-image-4.14.0-041400rc2-generic_4.14.0-041400rc2.201709242031_amd64 , headers all, generic) 3. It was a big issue to boot because apparmor seems to block most things like dhclient so its difficult to get an IP address. Needed to manually run dhclient after boot in terminal with this kernel
4. Ran my program (using xhost +) initially to get around a new sudo restriction 5. Following bug occured (below) Will keep investigating...
