Alien is a computer program that converts between different Linux package formats. It supports conversion between Linux Standard Base, RPM, deb, Stampede (.slp), Solaris (.pkg) and Slackware (.tgz) packages. It is also capable of automatically installing the generated packages, and can try to convert the installation scripts included in the archive as well. The latter feature should be used with caution since Linux distributions may vary significantly from one another, and using install scripts automatically converted from an alien format may break the system.Alien can be installed from universe repository. You will need to enable it first. After enabling universe repo do:
sudo apt-get updateThis will install alien. After installing alien you can convert rpm to .deb using command
sudo apt-get install alien
sudo alien -k package-name.rpmThis will generate a new file named package-name.deb. The -k option is used to keep the version number, otherwise alien will add a 1 to it. Using --scripts option will also include scripts from rpm into .deb.
sudo alien -k --scripts package-name.rpm
