[Bug] ubuntu_install_rocm.sh fails when generating ci-gpu image

[leandron]

The nightly Docker image rebuild job is failing for the ci-gpu with the following error:

 ---> Running in 4087679497b3
Warning: apt-key output should not be parsed (stdout is not a terminal)
gpg: no valid OpenPGP data found.
The command '/bin/sh -c bash /install/ubuntu_install_rocm.sh' returned a non-zero code: 2
ERROR: docker build failed.
script returned exit code 1

Looking at the history of the file, can either @jtuyls or @tqchen help with understanding what is going wrong?

OK, so it looks like http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key disappeared, and this script then needs updating.
