After I updated my apache, none of my virtual hosts are accessible anymore, the server responds "Connection refused". No errors are in the logs and I have no idea what is causing this. My virtual host is something like this:
<VirtualHost 173.XXX.XXX.XXX:80>
....
ServerName hostname.com
....
</VirtualHost>
<VirtualHost 173.XXX.XXX.XXX:443>
....
ServerName hostname.com
....
</VirtualHost>
Any ideas of how to debug?
"Connection refused" would mean that apache is not listening on port 80; run this command to make sure" lsof -i:80, if you found no output then start apache and try again
Update: after seeing some output of different commands; it turned out that libapache2-mod-php5 is not installed according to dpkg -l | grep apache2 it was flagged as 'rc' (removed, but configuration files remaining).
Since the debug information was showing loading mod_php5 then the absence of this package is what causing apache not to start
service apache2 start and returned "Starting web server apache2 [OK]", after I tried pgrep apache and no output was shown. Is apache not being initialized, even saying [OK]?!

Do you have your "Listen" directives in your vhost files or in /etc/apache2/ports.conf?
You should have a line similar to :
Listen 80
I get this problem every time I get a major upgrade/update on Ubuntu. Solved it just by running the following command:
sudo a2enmod ssl
sudo a2enmod rewrite
sudo /etc/init.d/apache2 restart
Hope this helps!
Another problem I found was that my lightdm stopped working. No GUI prompt after "apt-get upgrade". I found that lightdm was removed. I installed manually and all started working.
