Issue:
Replace use of deprecated apt-key
The use of apt-key has been deprecated for two years, so it would be good to update. Debian's official advice is [here](https://wiki.debian.org/DebianRepository/UseThirdParty).

See for example https://askubuntu.com/questions/1328806/how-to-solve-apt-key-deprecated for an approach that I think should work well for Ubuntu.

The apt commands written to the hppcm Docker build file need to be changed accordingly.
