Side-effects on tools that use gpg.

I have very little knowledge of gpg, so sorry if I'm confused. When running with hiera-gpg enabled, I can't install keys for different apt sources, it seems to have effected the environments gpg settings. I tried changing the permissions on /etc/puppet/gpg, but do to the way it's mounted, it's not owned by root.

BTW, hiera-gpg itself is working fine.

I think I found the culprit:

Believe we can just backup and restore the ENV and all will be well. Testing that theory now.
