Install on Linux (x64)
Fastest — one command
Paste this into your terminal and press Enter. It downloads TetherBay for Linux, unpacks it into ~/.local/opt/TetherBay, and tries to open it. Root access is not required. Check that the app window appears.
curl -fsSL https://tetherbay.com/get.sh | sh
Prefer to unpack it yourself? The manual steps below still work.
