I'm on ubuntu 22.04, using multipass 1.10.1 with a cloud-init file to instanciate a simple server:

users:
  - name: ubuntu
    ssh_authorized_keys:
      - ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOkF+W1ETkZQr5PWhcugCVh3aSyNDFTYQRRblh7prGXN
    ssh_import_id:
      - lp:nrobinaubertin

I launch the instance with:

multipass launch -n simple_instance -d 10G -m 1G -c 1 --cloud-init cloud-init.yaml 22.04

And I check the authkeys file with:

multipass exec simple_instance -- cat /home/ubuntu/.ssh/authorized_keys

The key from ssh_authorized_keys is there but not the one from ssh_import_id. From the documentation website and the examples given here I would expect both keys to be present.

Thanks, nrobinaubertin, for reporting this.

Could you please attach the instance logs[1]?

Thanks, nrobinaubertin. I have reproduced this behavior on multipass and lxd.
