Skype is proprietary software and must be installed manually
on Ubuntu
How can I use Skype on Ubuntu?
Skype is proprietary software that allows you to make calls over
the Internet using your computer.
Skype uses decentralized peer-to-peer technologies, so your calls do not go
through a central server, but through distributed servers and other users.
The Skype software is free to use, but it is not free software; the source
code is proprietary and not available for modification.
Skype is not installed by default on Ubuntu. Follow these steps to install
Skype for Linux:
Open your web browser and go to the Download Skype page.
Click the Get Skype for Linux DEB button.
In the window which shows up, select Open with and Software
Install (default), and then click the OK button.
Ubuntu Software is opened. Click the Install button and authenticate.
