# Installation of repositories

1. Download an installer script:

   wget https://repo.tuxcare.com/ubuntu20_04-els/install-ubuntu20.04-els-repo.sh
   

2. Run the installer script with keys. The installation script registers the server in the CLN with the key, adds PGP key to the server.

   bash install-ubuntu20.04-els-repo.sh --license-key XXXX-XXXXXXXXXXXX
   

3. Verify that the installation was successful. To ensure that installation has been completed successfully, run the following command:

   apt-cache show els-define
   

   It should return the info of an available package. If you see information about the package, you can be sure that the installation was successful. After this, you will be able to install updates from the repository using a regular apt upgrade command.
