[Stuart Bishop]

Looks like we are missing the Python OpenSSL library

I've confirmed this is still an issue in cs:apache2 and is triggered if you're using the self-signed certificate option

Adding apt_get_install("python-openssl") to the install_hook function in hooks/hooks.py should fix it.

We've fixed this in cs:~apache2-charmers/apache2 and are requesting promulgation of that charm. The location for bugs will change as a result too.
