Source files typically come as file types called Tar Balls, which end in either the TAR or TAR.GZ extension. The Ubuntu version of Linux is a Debian based Linux system and as such uses the DEB based packages and libraries, not RPM (like RedHat Fedora, openSuSe, etc.). The file inside are similar to what you'd see inside a windows EXE file. You can look inside them like a zip file, sure, but the files are all designed around an assumptive process that your system uses specific RPM libraries so trying to 'compile from source' using these will throw a gazillion errors.

An RPM file is a pre-configured installer package for systems that use RPM packages. Let's define a few things then I'm pretty sure I have a solution for you:Īn RPM file is not a source file, nor is it a zip file.
