I can confirm this is related to llvm bug (at least in my case) and seems to happen on i7 skylake (6th generation). I have 16.04 live image installed on usb and had the same problem - illegal instruction in plasma. I managed to solve this simply by updating libllvm3.8 from 1:3.8-2ubuntu1 to 1:3.8-2ubuntu3 (i had persistent storage enabled on the usb).
Once 16.04.1 iso is out, this will probably be resolved as it should (hopefully) contain updated version of libllvm. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1571564 Title: Unable to install Kubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-meta/+bug/1571564/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
