After I change /etc/apt/sources.list...why doesn't it take effect?

Question

Do I have to restart something?

Edit: sudo apt-get update has no effect.

When I search this on another machine with the SAME sources.list, it works. But, it still doesn't work on this machine.

sudo aptitude search sun-java6-jdk

Answer 1

Maybe you forgot to run "apt-get update"...

Answer 2

After editing any configuration files in /etc/apt, you generally need to do an update;

apt-get update

This allows apt to update itself, it's configuration and the server(s) it queries for packages.

Answer 3

You might want to double check that you've got the multiverse repository included. The sun packages are in that one. For example, if you've got:

deb http://www.gtlib.gatech.edu/pub/ubuntu/ jaunty main restricted

you can tack on multiverse to the end to add it.

deb http://www.gtlib.gatech.edu/pub/ubuntu/ jaunty main restricted multiverse
