Ubuntu Support only deb package installation, If you have some software in rpm package you can install it in Ubuntu easily. Fedora/Redhat and Mandriva support RPM packages.

In Ubuntu you can easily install softwares from Software Centers or via PPA. If any software is not available in deb/software center/ppa and it’s only available in rpm, than you can easily convert that rpm file to deb package with one command using terminal.
