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

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

  • That still doesn't work.

  • What did you add to /etc/apt/sources.list? Oct 14, 2009 at 21:06

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.


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
