[Ubuntu] How to extract .7z 7 zip files

First install the

Code:

p7zip-full

package:

Code:

sudo apt-get install p7zip-full

With this, Nautilus should have an option to uncompress 7-Zip Files.
I also recommend

Code:

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:

Code:

7z x PACKAGE.7z

that should eXtract the packages with full path.
