Installed repositories for sudo apt-get. E: Invalid operation
 

Hi im on an asus eeepc 900a running Xandros, and everytime i sudo apt-get install i get E: Invalid operation. So i followed the steps on http://wiki.eeeuser.com/addingxandro...20repositories
i did the last sudo apt-get update, tried to sudo apt-get install comix and still get E: Invalid operation
Im lossed hope i didnt screw up my system. Any help is appricated.

Got it guys, i answered myself, i had to simply log in as su and apt-get my package even know sudo allows a permitted user to execute a command as the superuser, i had to manualy login as su

Good to see it works.
