microstack requires password for cirros with stock installation

[Aryeh Hillman]

**Observed behavior**:

Despite using key auth, a password is requested for an ssh session for cirros

**Expected behavior**:

An ssh session against cirros without a password using ssh key auth

**Other info**:

I am using this guide: https://ubuntu.com/openstack/install exactly. The issue is during the "connect to the instance" step.

```

Update: I was able to log in with the password `gocubsgo`. I found it by navigating to the openstack http server, clicking on the instance, and viewing the console.

Looks like merely a docs issue.

[Maurice Miller (mauricemiller)]

Not sure if you found a solution for your issue, I found this on the net;

$ ssh -o "PubkeyAcceptedKeyTypes +ssh-rsa" -i /home/guardian/snap/microstack/common/.ssh/id_microstack cirros@10.20.20.220

Change the obvious to your environment and it should work. The documentation should reflect the difference between Ubuntu 20 and Ubuntu 22 installations. On Ubuntu 20, ssh auto authenticates as you would expect it too, on Ubuntu 22, it does not seem to be auto authenticating.
