Skype is not an open-source application, and it is not included in the default Debian repositories. We’ll install Skype using the Skype deb package.
Download Skype deb package:
wget https://go.skype.com/skypeforlinux-64.deb
When the download is complete, install Skype using command:
sudo apt install ./skypeforlinux-64.deb
Now run Skype and authorize with your login, that’s all
