Debian is a free GNU / Linux operating system that provides more than 51000 program packages, compiled and ready for installation and use on your machine.
It is a result of Debian Project, and is one of the most popular Linux distributions.
Few about History
Debian as a project started on 16 August 1993 by Ian Murdock, then Purdue University student. He then wrote the Debian Manifesto, which called for the creation of a linux distribution that would develop in a way open to the spirit of GNU / Linux. Jan Murdock chose the distribution name by combining the name of Debra's then girlfriend with his own (Ian).
Let's say Ian's operating system is based on very large and popular distributions like Ubuntu and Linux Mint. You can add to them almost other 130 Linux distributions.
Below we will see what you can do right after you install it new, stable version of Debiye 9.
"After 26 development months, the Debye project presents the new stable 9 (code name Stretch) version, which will be supported for the next 5 years thanks to the combined work of the Debian Security team and the long-term support of the Debiye team."
Debian 9 Full DVD ISO (need only the first)
9.1 contains all the improvements to the first version of 9, so you will not need to upgrade the packages by installing your new system.
Let's just hurt the Source List
We will add "contrib" and "non-free" repositories that are not 100% FOSS (Free and Open Source Software) according to the Debian Free Software Guidelines (DFSG).
Cont Contos contain packages that comply with the DFSG, but may depend on packages that are not free or require non-free packages for their construction.
Non-free repos contain packages that do not comply with DFSG
If you want your installation to be 100% FOSS as stated in the Debian Free Software Guidelines then do not add "contrib" & "non-free" to the source list.
We will open sources.list for editing with nano:
enter your root password and
You will see the image below, or rather the goal is to make the sources.list you use like the edited image:
How can this happen;
First remove the first rows showing the packet installation path from the DVD, CD.
Your nano mouse can be moved with the arrow keys…
Then, in 3, grouped links check the # second of each row to disable source repos.
On the first rows of 3 groups now add it contrib non-free in the first and the non-free in the second and third.
Save with CTRL + X, then y and then enter.
Give Sudo Access your name
apt-get install sudo

apt-get install file-roller evince geany pinta qalculate clementine vlc gimp shotwell gparted gnome-disk-utility libreoffice-writer libreoffice-calc libreoffice-impress
Installing TeamViewer in Debian 9
Here's how this installation works because the application is i386.

apt install libjpeg62-turbo:i386 wget gdebi-core
TeamViewer download and install
wget https://download for free.teamviewer.com/download for free/teamviewer_i386.deb
