[plug] ubuntu package install question

[Chris Griffin]

I have managed to install ubuntu and wanted to install the latest Java
runtime. I have a .rpm of it and have managed to try to tell ubuntu to
install the rpm. It told me I needed to use alien on it, I did and now
I have a .deb of that file. So what now?
I have tried to use Synaptic package manager but it only wants to look
on the net for packages to install.
Any help appreciated.
