For anyone still reading this in 2024 and are beginners to this certain aspect of software I made these instructions work. There are some small changes due to updates. Here is a copy and paste that I left in the video with time stamps.
Works great with current as of March 09 2024 with small changes. Pros may not need the help but it’s good for people like me. 3:30 No quotation marks (speech marks) needed around the pasted keys. 4:47 It’s now in folders Connections > SSH > Auth > Connections 5:21 I also changed the user name from root to something of my choosing as recommended by the program. I just made sure to add it in the SSH configuration settings on my home assistant under settings for ssh and command program that I use.
