How to Uninstall and Install keychain Ubuntu 22.04

Updated: September 19, 2022

Keychain is an OpenSSH key manager, typically run from ~/.bash_profile. When keychain is run, it checks for a running ssh-agent, otherwise it starts one. It saves the ssh-agent environment variables to ~/.keychain/${HOSTNAME}-sh, so that subsequent logins and non-interactive shells such as cron jobs can source the file and make passwordless ssh connections. In addition, when keychain runs, it verifies that the key files specified on the command-line are known to ssh-agent, otherwise it loads them, prompting you for a password if necessary. I will show you how to install keychain on Ubuntu 22.04 in this tutorial.

Prerequisites

  • OS: Ubuntu 22.04 or older Ubuntu versions
  • Privileges: Check that you can run sudo commands.
