Aborting…

I’d recommend just downloading the binary:
https://download.blender.org/release/Blender2.79/

The Blender project does not maintain these packages in Linux distributions, and generally there will not be much support for building versions that are a few years old. So it’s somewhat unlikely you’ll get a good answer to the question here.
