Crouton broken by Chrome OS security update – here’s a fix

A security update in Chrome OS 73 patches a security hole used to run the Crouton script. Luckily, it’s easy to work-around with a simple permission change on the Crouton file.

  • Use CTRL+SHIFT+T to open the terminal window like normal.
  • Then type shell like you normally would.
  • Enter the following to alter the permissions in order to allow you to run the Crouton script:
sudo install -Dt /usr/local/bin -m 755 ~/Downloads/crouton

You’re done! Now you can update Crouton or install targets as you would normally.

My article on how to setup Crouton and Steam on a Chromebook has been updated to reflect this change.
