Comment 2 for bug 1836329

I followed [1] to do some checks against the version reported to be bad.

The easiest copy and paste setup would be:
$ apt install apache2
$ IP=$(hostname -i | cut -d' ' -f 2)
$ sed -i -e "/ServerAdmin/a ServerName $IP" -e 's/ssl-cert-snakeoil.pem/apache-selfsigned.crt/' -e 's/ssl-cert-snakeoil.key/apache-selfsigned.key/' /etc/apache2/sites-available/default-ssl.conf
$ sed -i -e "/ServerAdmin/a Redirect \"/\" \"https://$IP/\"" /etc/apache2/sites-available/000-default.conf
$ sudo cat << EOF > /etc/apache2/conf-available/ssl-params.conf
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
SSLHonorCipherOrder On
Header always set X-Frame-Options DENY
Header always set X-Content-Type-Options nosniff
SSLCompression off
SSLUseStapling on
SSLStaplingCache "shmcb:logs/stapling-cache(150000)"
SSLSessionTickets Off
EOF
$ (sleep 2s; printf "\n"; sleep 2s; printf "\n"; sleep 2s; printf "\n"; sleep 2s; printf "\n"; sleep 2s; printf "\n"; sleep 2s; printf "$IP\n"; sleep 2s; printf "\n";) | sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
$ sudo a2enmod ssl
$ sudo a2enmod headers
$ sudo a2ensite default-ssl
$ sudo a2enconf ssl-params
$ sudo apache2ctl configtest
$ sudo systemctl restart apache2

The above works in a LXD container and would give a basic setup to test.
Basic usage of this server was fine for me, doing some ssl checks now ...
