Distribution: Red Hat 9.0
I got spoiled already by using Fedora3 which has a lot of stuff available right from the start.
If you can, I would recommend that you do a fresh install ( not upgrade from 9.0 ) of Fedora 3.
It is the best version of Redhat yet! IMHO of course.
If you still want the apt-get and synaptic tools installed on RH9.0 , do a google search for
pbone apt-get rpm
then download the rpm file and install it.
Then you run the command as root user: apt-get update and apt-get install synaptic
