Describe the bug

The Github Actions CI and Dockerfiles seem to rely on softhsm as a package for the HSM tests.

In a PR I recently opened this was a failure as the package could not be found. The version of Ubuntu is not pinned, although I'm not sure why the failure wasn't caught prior to my PR as my PR has nothing to do with that CI workflow AFAIK?

The Docker images use Debian as a base where softhsm is still a valid package name, there's also softhsm2 there and the softhsm debian package does bring in softhsm2 implicitly.

The last version of Ubuntu with the softhsm package appears to be 16.04. Github Actions test runner is using ubuntu-latest. All newer versions of Ubuntu pacakge that binary in the softhsm2 package.

Reproducing the bug

Both Ubuntu and Debian have a softhsm2 package, only Debian has the softhsm pacakge (brings in softhsm2). Should be resolved and consistent with all package installs preferring the softhsm2 package instead.

Ubuntu failure:

$ docker run --rm -it -e DEBIAN_FRONTEND=noninteractive ubuntu:24.04 bash -c 'apt-get -qq update && apt-get -qq install -y softhsm'

E: Unable to locate package softhsm

Ubuntu success by using softhsm2 instead of softhsm:

$ docker run --rm -it -e DEBIAN_FRONTEND=noninteractive ubuntu:24.04 bash -c 'apt-get -qq update && apt-get -qq install -y softhsm2'

Happy to switch to softhsm2 if it keeps working in the tests :)
