I always use SSH on my Hassbian image. Since the last upgrade to 0.65.5 this does not work anymore. I still use user pi and password raspberry. Have not added keys yet. Anything changed?
Forgot to say always get a permission denied now…
A simple home assistant upgrade shouldn’t touch the underlying OS. SSH is a component of the underlying OS and not home assistant.
You will probably need to hook up a monitor and keyboard to troubleshoot
