Tip: “Sudo” is short for SuperUser DO or Substitute User DO and is a prefix used to run commands with the permissions of other users. Note: The Linux VPN client is still in beta and may have bugs or be unstable. The guides are easy to read and uncluttered, although the non-Ubuntu guides are unclear as to which commands need to be prefixed with “sudo”. Windscribe offers guides to install its command-line based Linux VPN for 6 different versions of Ubuntu along with guides for three other Linux distributions. You should always be wary of command suggestions from third parties.

Advice and commands provided by the official VPN providers can generally be trusted, although it’s still good practice to understand what commands you are running. Sudo’d commands can potentially even corrupt the firmware on your motherboard, so you should be careful. This is doubly important when the command is prefixed with the word “sudo” as these commands run with full root permissions and can break your operating system. Tip: It’s recommended that you never run any commands that you don’t understand.
