Install Skype Ubuntu

Skype is the most famous application for communication around the world. It's cross-platform and available on macOS, Linux, and Windows. We can make online video and audio calls at no cost as well as international calling to landline and mobiles worldwide with Skype. Skype isn't any open-source app and it's not contained in the standard repositories of Ubuntu.

While Skype is free to Skype instant messaging and calls, but we must pay for using a few features like calling Skype outside to landline or mobile phone numbers or sending text SMS.

Note: Skype by default doesn't come installed on Linux operating systems.

In this article, we will show some ways to install Skype in the 20.04 version of Ubuntu. Skype could be installed and downloaded as a snap package by the deb package or Snapcraft store from the repositories of Skype.

We can select the method of installation that is most convenient for our environment.

What is Skype?

Skype can be described as an application of proprietary telecommunications that specializes in giving VoIP-based videotelephony, video calls, and videoconferencing. Also, it has file transfer, instant messaging, debit-based calls to mobile and landline telephones (on traditional telephone networks), and various other features.

This application is available on several mobiles, desktop, and console platforms of video games and it is implemented by 'Skype Technologies' which is a Microsoft division. Skype Was utilized by a hundred million users on a monthly basis and by forty million users on a daily basis as of 2020 March.

Skype was the establishment of Janus Friis and Niklas Zennstrom in relation to four Estonian developers and was initially published in 2003 August. eBay inherited Skype for 2.6 dollars billion in 2005 September. Canada Pension Plan Investment Board, Andreessen Horowitz, and Silver Lake announced the 65% acquisition of Skype for 1.9 dollars billion by eBay, which featured to the organization a market value of 2.92 dollars billion.

Microsoft purchased Skype in 2011 May for 8.5 dollars billion, substituting the Windows Live Messenger with Skype. Almost all the teams of the development and 44% of each employee of the division are still positioned in Estonia, Tartu, and Tallinn as of 2011.

Originally, Skype provides a hybrid client-server and peer-to-peer system. Entirely, it became powered via Microsoft-implemented supernodes in 2012 May and transitioned Skype through a peer-to-peer service to a consolidated Azure-based service in 2017.

Note: Skype lost a big segment of its market share to the Zoom application during the pandemic of the COVID-19.

Skype Features

  • Registered Skype users are recognized by a specific ID of Skype and might be listed within the directory of Skype under the username of Skype.
  • Skype permits the registered user for communicating from both voice chat and instant messaging.
  • Voice chat permits telephone calls among user pairs and conference calling and applies proprietary audio codec.
  • The text chat client of Skype permits storing chat history, emoticons, group chats, and editing the old messages.
  • Messages (offline) were implemented within the 5th version of the beta build but deleted after some weeks without any notification.
  • The regular aspects familiar to the uses of instant messaging-online status indicators, user profiles, and so on-are included as well.
  • The Skypeln online number service permits the users of Skype for receiving calls on their systems dialed by the subscribers of the conventional phone to a Skype phone number (local); local numbers exist for Netherlands, Turkey, Switzerland, Sweden, Korea South, Africa, Romania, Poland, New Zealand, Nepal, Mexico, Japan, Ireland, India, Hungary, Hong Kong, Germany, France, Finland, Estonia, the Dominican Republic, Denmark, Colombia, Chile, Brazil, Belgium, Australia, United States, and the United Kingdom.
  • A user of Skype can have many local numbers in these countries, along with calls to a number charged at a similar rate as calls to settled lines within the country.
  • The Skype application provides its support for video chats, conference calls, and screen sharing among 25 users at a time at no cost, which expanded to 50 in 2019 on 5 April.
  • Skype doesn't facilitate the ability for calling emergency numbers like 112 in Europe, 100 in Nepal and India, 999 in the UK, and 911 in North America.
  • As of 2012 December, there is restricted support for all emergency calls in Finland, Denmark, Australia, and the United Kingdom.

The Federal Communications Commission (short for FCC) of the US has ruled that the Skype application is not an "interconnected VoIP provider" for the aim of Telecommunications Act section 255. The National Emergency Number Association of US recommends as a result that every user of VoIP has an analog line present as a backup.

Skype included an option for blurring the background inside an interface of video chat with AI algorithms implemented using software in 2019, against a camera (depth-sensing) not being available in almost all webcams.

Protocol of Skype

Skype applies a proprietary VoIP (Internet Telephony) network which is known as the 'Skype Protocol'. This protocol hasn't been developed publicly present by Skype and all official applications with the protocol are proprietary as well. Skype technology part depends on the protocol of Global Index P2P belonging to the corporation of Joltid Ltd.

The primary difference between is standard VoIP and Skype clients is that Skype works on a peer-to-peer concept (which is originally based on Kazaa software) instead of the more regular client-server concept.

Note: The very famous Session Initiation Protocol (short for SIP) concept of VoIP is peer-to-peer as well, but implementation normally needs registration using a server.

Install Skype as the Snap Package

The snap package of Skype is maintained and distributed by Microsoft. Snap is a self-contained package of software that contains the binary of each dependency required to execute the application. Snap package is secure and easy to upgrade. Snap has a larger footprint of the disk and longer start-up time of the application, unlike the standard packages of deb.

Snap packages could be installed using either via the Ubuntu Software application or the command-line.

Snap can also be described as an application packaged with every required library and dependency. We will require to have snap installed on our system for installing any snap package. In the 16.04 and later versions of Ubuntu, the snap has already been installed. If the snap package is not available on our system, then we can install it with the help of the below command:
