tap2junit fails to install on rhel8-x64 machines

[richardlau]

Ansible playbook fails to install tap2junit on the rhel8-x64 machines (I've tried all three IBM hosted ones and the Digital Ocean machine).

I suspect the problem is that /usr/libexec/platform-python is being used, which is Python 3.6 on RHEL 8. We do have Python 3.9 installed on those machines:

$ ssh test-digitalocean-rhel8-x64-1 python3 --version
Python 3.9.13
$ ssh test-digitalocean-rhel8-x64-1 /usr/libexec/platform-python --version
Python 3.6.8
$
