So I know I probably should have left well enough alone. But I decided to perform an in place upgrade from 10.04 to 12.04 and now I'm paying for it.
Generally everything else seems fine, except apache.
When I try to start (as root) this is what I get.
ve : /etc/init.d/apache2 start
* Starting web server apache2 mktemp: failed to create directory via template `/var/lock/apache2.XXXXXXXXXX': No such file or directory
chmod: missing operand after `755'
Try `chmod --help' for more information.
