title: installing updates on multiple ubuntu machines
body: <p>I am trying to find out if there is a way to connect with multiple ubuntu machines and install updates simultaneously.</p>
  
  <p>Ideally, if I enter a command "sudo apt-get update" from one machine, it should execute in all the ubuntu machines that I am connected to.</p>
  
  <p>I looked at TMUX but not sure if that would be appropriate. Also found apt-cacher but connecting with other systems using their IP remains unclear.</p>
  
  <p>any help and reference will be appreciated.</p>
