Cannot start pritunl service ImportError: libffi.so.6

I cannot start my pritunl service. I have Ubuntu 20.04.6 LTS and pritunl:amd64/bionic 1.32.3602.80-0ubuntu1~bionic

systemctl -l status pritunl

Gives me:

ImportError: libffi.so.6: cannot open shared object file: No such file or directory

This seems to be a python-related issue, but I have no idea how to fix it!

Many thanks,
Justin

Ubuntu Bionic is 18.04, Focal is 20.04. Verify that the apt repository file for the Pritunl repository matches the correct distribution listed in the repositories documentation. Then reinstall the Pritunl package.

Fantastic, thats got it, many thanks indeed for your help!!
