Comment 1 for bug 1889645

Focal is shown as supported, but it fails to install:

ERROR juju.worker.uniter.operation hook "install" (via explicit, bespoke hook script) failed: fork/exec /var/lib/juju/agents/unit-sca-dp-fe-openid-0/charm/hooks/install: no such file or directory

the actual error is that's trying to use plain "python" interpreter:

# ./hooks/install
bash: ./hooks/install: /usr/bin/python: bad interpreter: No such file or directory
