ubuntu

On a new install of Amahi on Ubuntu 12.04.2 (is this a supported scenario?), running:

sudo service apache2 restart

 * Restarting web server htcacheclean
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
[Wed Apr 03 11:53:57 2013] [warn] NameVirtualHost *:80 has no VirtualHosts
[Wed Apr 03 11:53:57 2013] [warn] NameVirtualHost *:80 has no VirtualHosts
 ... waiting /var/lock/apache2 already exists but is not a directory owned by apache.
Please fix manually. Aborting.
                                                                         [fail]

The workaround I've found is to:

sudo rm -R /var/lock/apache2
sudo service apache2 start

Weirdly, both while apache is stopped and after it is running again, ls -la /var/lock shows
