Comment 1 for bug 1869115

This is now an issue in Ubuntu 18.04 as well. I'm guessing whatever broke was backported into 18.04 as well.

See these scripts as examples:

Version for 18.04 and 20.04:

https://raw.githubusercontent.com/earnolmartin/EHCP-Force-Edition/master/ehcp/etc/pam/pam_dbauth_vsftpd_ubuntu_20_plus.py

Version for 16.04:

https://raw.githubusercontent.com/earnolmartin/EHCP-Force-Edition/master/ehcp/etc/pam/pam_dbauth_vsftpd.py

Difference is that in 18.04 and 20.04, I must set the path in the script:

sys.path.insert(0, '/usr/local/lib/python2.7/dist-packages')
sys.path.insert(0, '/usr/lib/python2.7/dist-packages')

If I do not, I get this error:
