We usually install programs in ubuntu by using Synaptic or running apt-get command in terminal.Unfortunately,we can’t install an RPM package by these ways.
To install an RPM package,first we need install a utility that change packages from one format to the other.
sudo apt-get install alien dpkg-dev debhelper build-essential
Run following command in terminal to change the format of the package.
sudo alien filename.rpm
A new package generated with .deb extension.Now install the .deb package:
sudo dpkg -i filename.deb
