I've set up ubuntu 5.04 at a Virtual Machine created with VMWare 5.0. running over W2000. At this Virtual Machine I've tried
setting up Postgresql but when I open a Root Terminal and I write this inside

root@nombre:/# sudo apt-get install postgresql
>> (without sudo this make the same)

Obtain the next results:

Reading package list... Done
Making Dependence Tree... Done

Postgresql package is not available. but any one package has referenced to it. This could mean that is a faulting package
or package is obsolete or package is only available from another source. Package postgresql hasn't proposal installer for
your set up

What could I do to resolve this postgresql problem? If it is necessary How could I get the Postgresql package? Thanks y Rgrds
