Comment 60 for bug 77675

The way to do this has changed. The procedure is still simple for a self signed ssl cert.

The following is the correct way:

apt-get install apache2
a2enmod ssl
a2ensite default-ssl
make-ssl-cert generate-default-snakeoil
/etc/init.d/apache2 restart

You can find this in the follow doc under SSL:
/usr/share/doc/apache2.2-common/README.Debian.gz
