I know this is late and sorry about that, just upgraded myself to new 18.104.22.168 and until now everything has worked with the gnutls. I upgraded and reconfiged and made a new cert then towards the end of the upgrade I was confronted with:
Restarting web server: apache2We failed to correctly shutdown apache, so we're now killing all running apache processes. This is almost certainly suboptimal, so please make sure your system is working as you'd expect now! (warning).
Syntax error on line 47 of /etc/apache2/sites-enabled/000-ispconfig.vhost:
Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration
... waiting failed!
So similar issue with Debian 5 is what I am running. When following the directions in the first post I disabled ssl with:
And enabled gnutls:
Well the upgrade broke my sites and ISPConfig. Could not start apache. What I did for right now is re-enable ssl and apache was able to start without error:
# a2enmod ssl
Enabling module ssl.
See /usr/share/doc/apache2.2-common/README.Debian.gz on how to configure SSL and create self-signed certificates.
Run '/etc/init.d/apache2 restart' to activate new configuration!
l# /etc/init.d/apache2 restart
Restarting web server: apache2 ... waiting .
Try that to see if you are able to get everything back up.
Also I will post any updates I have about getting gnutls back in order.
Hope this helps.
