TeamViewer is a global remote connectivity platform that provides secure access to any device globally. It’s used for online meetings and file sharing between computers and remotely controlled instrumentation such as robots or industrial machinery via VPN connections (virtual private networks).
The following tutorial will teach you how to install TeamViewer on Ubuntu 20.04 LTS Focal Fossa. The tutorial will import the official repository and gpg key and update and remove the remote desktop software using the command line terminal.

Before proceeding with the tutorial, ensuring your system is up-to-date with all existing packages is good.
sudo apt update && sudo apt upgrade -y
Install Required Packages
The following dependencies will need to be installed. Most of these packages are already on your system, but running the command can help ensure they’re installed.
sudo apt install wget apt-transport-https gnupg2 -y
If you skip and encounter issues, return and just run the command.
The first step is to import the GPG key to verify the authenticity of the packages. In your terminal, execute the following command to import to your keychain.
sudo wget -O- https://download.teamviewer.com/download/linux/signature/TeamViewer2017.asc | gpg --dearmor | sudo tee /usr/share/keyrings/teamview.gpg
Next, import the repository.
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/teamview.gpg] http://linux.teamviewer.com/deb stable main" | sudo tee /etc/apt/sources.list.d/teamviewer.list
Now run an APT update to reflect the newly imported repository.
sudo apt update
Finally, you can install the TeamViewer using the following command.
sudo apt install teamviewer -y
Note that you may see a keep source or import maintainer during the installation. Ideally, choose to compare changes; keep the original if they are still the same.
Type N for no to proceed, do not enter yes for the answer, or you will replace the source list format with a less secure one that may not work with your system for future updates.
How to Launch TeamViewer
Launching can be done in a few ways now that you have the software installed.
Using the command line terminal, you can open it quickly by using the following command.
The best way to use TeamViewer for desktop users that prefer not to use the command line terminal is to open the GUI of the application by following the path.
Activities > Show Applications > TeamViewer.
Once open, you can begin connecting with TeamViewer; ensure you reset your password when you give it out to remote people who need to connect to your system after they have finished.
For novice users or users new to computing, remember to proceed with caution with who you give your details. This goes for any software of this type, and it is highly recommended to use the refresh button on the password to generate a new one every time someone externally has finished.
How to Update/Upgrade TeamViewer
The software should update by itself with your system packages for desktop users using the APT package manager. For users who want to check manually, use the following command in your terminal.
sudo apt update && sudo apt upgrade
How to Remove (Uninstall) TeamViewer
When you no longer want the video conference software installed on your system, use the following command to remove it.
sudo apt autoremove teamviewer --purge -y
Remove the repository if you plan not to re-install the software again.
sudo rm /etc/apt/sources.list.d/teamviewer.list
After removing the repository list file, remove the GPG.
sudo rm /usr/share/keyrings/teamviewer.gpg
