How do you install Surfshark VPN on Linux?

To install Surfshark VPN on a Linux machine, start by opening the terminal. The user should first ensure their system is up to date by running `sudo apt-get update` and then `sudo apt-get upgrade`. After updating the system, they can download the Surfshark repository setup file using a command like `wget https://repo.surfshark.com/debian/pool/main/s/surfshark-release/surfshark-release_1.0.0-2.1_all.deb`. Once the file is downloaded, proceed with installing the repository by typing `sudo dpkg -i surfshark-release_1.0.0-2.1_all.deb` into the terminal. Next, they'll need to run another update with `sudo apt-get update` to refresh the package list with the newly added Surfshark repository. Following this, install the Surfshark VPN client with `sudo apt-get install surfshark-vpn`. To finalize the installation, activate the Surfshark service using the command `sudo systemctl enable --now surfsharks-VPN@service`. At this stage, Surfshark is installed on the Linux system, and users can log in and connect to a VPN server using provided command-line instructions or via the Surfshark application interface.
