While installing fred on Ubuntu using install script, it always times
out at this line:
     apt-key adv --keyserver 
keyserver.ubuntu.com --recv-keys
F20C079E020ADBB4
After doing some R&D, I was able to make it work by changing this line
to:
     apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys
F20C079E020ADBB4
Hope this will help friends who may face same situation.
