How to install a .rpm file in your Ubuntu?
Step 1: Install the alien package
$sudo apt-get install alien dpkg-dev debhelper build-essential
locate your .rpm file and do the following command.
$sudo alien filename.rpm
And blast!!!! You have now your .deb package instead of a .rpm one.
Now it’s ready to be installed using the dpkg command.
$sudo dpkg -i filename.deb
