The repository signing key used for the CUDA RPM and Deb packages has been updated to reflect modern standards. As a result, package managers may have problems with installing or upgrading CUDA 8 packages. Follow either of the options before proceeding further.
If you are a Linux user, click to see instructions in this section before proceeding.
Option 1

Systems with repositories updated with CUDA 8.0 need to download and re-install the 'cuda-repo-*' package for your distribution of Linux. Re-installation of this package will import the new signing key with ID 7fa2af80.

Option 2

Manually import this key by downloading the file 7fa2af80.pub from the appropriate repository (for example, Ubuntu 14.04 x86_64 would be http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/7fa2af80.pub) and then running, as root:

a) For Ubuntu distributions: `cat 7fa2af80.pub | apt-key add -`
b) For Fedora, RHEL and SUSE distributions: `rpm --import 7fa2af80.pub`

At a future date, CUDA packages will begin removing the old public key with ID 5C37D3BE. If you are only using the newly signed repositories, it is safe to remove the old key manually by running, as root:

a) For Ubuntu distributions: `apt-key del 5C37D3BE`
b) For Fedora, RHEL and SUSE distributions: `rpm -e gpg-pubkey-5c37d3be`
