How to install Boundary on Ubuntu in 3 CLI commands

Press ctrl+alt+t to open a Terminal Emulator window in Ubuntu.

Then you can copy or type this in to install Boundary on Ubuntu Linux in a terminal:

curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -
sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main"
