How to set the SSH key of the root user during an automated 20.04 server install?

  • 772

I'm trying to write an SSH key to /root/.ssh/authorized_keys during an automated 20.04 server install, but it fails, probably because of permission problems.

The 1st command is successful, the 2nd fails:

  late-commands:
    - echo 'test2' > /target/etc/test2
    - echo 'ssh-rsa ...' > /target/root/.ssh/authorized_keys

How could I achieve that?

    I just had the same problem. It would certainly be better to solve this with the users block from could-init or user-data as mentioned here, but I couldn't get either of them to work.

    So I went with your solution and added a mkdir /target/root/.ssh to the late-commands. Not pretty but works.
