Hassbian Upgrade Problem

Hello,

My webclient is informing me that a Home Assistant update is available.

I have logged into my pi via Putty. When I run:

sudo systemctl stop [email protected]

it fails with the message “sudo: unable to resolve host hassbian”

I installed Home assistant via the "How to get started with home assistant usign HASSbian 1.1 on the BRUH Automation YouTube Channel.

This can be solved with this link
