Seems the most methods of installing Cuda 8.0 for Ubuntu 14.04 are failing:
ubuntu@host:~$ md5sum cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64-deb
407b939b35a887044653337db99b1338 cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64-deb
compared to the published checksum:
a4b9657a8ee026e0c97270b2d4174a8a cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64.deb
The Ubuntu 16.04 deb has the correct checksum however:
ubuntu@host:~$ md5sum cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb
d735c7fed8be0e72fa853f65042d5438 cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb
d735c7fed8be0e72fa853f65042d5438 cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb
Is it possible the 14.04 release of Cuda 8.0 has a bad build at the moment?
