Ubuntu apt-key not working? Behind a Firewall? Open port port 11371 or use http://:80

I was trying to get some Ubuntu PGP Key’s for some ppa.launchpad.net sources, and apt-key kept erroring out. All I had to do was open up 11371 on my firewall or just use http://keyserver.ubuntu.com:80 which would force the HTTP protocal instead of HKP.

It’s that simple actually.
