[linux] install 7z

First install the p7zip-full package:
sudo apt-get install p7zip-full
With this, Nautilus should have an option to uncompress 7-Zip Files.
I also recommend p7zip-rar so it also includes support for RAR files.
This is assuming you want to do it via GUI with Nautilus. If not, after downloading the packages above do the following:
7z x PACKAGE.7z
that should eXtract the packages with full path
