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...

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
