Alien converts a Debian package into a standard RPM package from source code and installs it using your distribution’s standard package management utilities. While distribution-specific packages from trustworthy repositories or compiling from source are to be preferred, alien gives you an option when the only thing available is a Debian package.
As root, “urpmi alien”.
To convert a Debian package to an RPM and install it, as root:
alien -ri PACKAGE_NAME.deb
Keep in mind that Debian and RPM packages each have capabilities that the other lacks, so something may be lost in translation.
