Installing RPM package in Ubuntu
I recently had to use my VPN client to connect to work but for some reason the VPN didn't work correctly. After some digging, I found out I need the need to install ncui rpm package (ncui-1.2-1.i386.rpm & ncui-6.5R6.i386.rpm). Unfortunately, I wasn't able to find the Debian package (.deb) so I had to find a solution.
Alien is the answer
First, let's install alien:
sudo apt-get install alien
Now we need to convert them to .deb package.
You can convert the rpm package to a Debian package by using the following commands:
sudo alien -k rpm-package.rpm
The "-k" option will keep the version number.
One the package is converted, you can install the Debian package by using the following commands:
sudo dpkg -i deb-package.deb
