This question already has an answer here:

I am using 16.04 lts, and after it wasn't working I deleted it on accident and now I do not have the Software Center nor any of my apps, (Inkscape, Blender, misc games.) My steam is running and programs that I downloaded before work.

    Have you tried any of the options here? – fakedad Nov 8 '16 at 3:30

Its not necessary for your computer to have internet connection. However access to internet (on any device) is obviously required to get the installation files.

If you could arrange .deb file of the Software Centre by asking your friend run this to install.

sudo dpkg -i /path-to-file/filename.deb
