Beginners • Re: On/Off Switch for Raspberry Pi 4

Make sure to use <username>@localhost, not <username>@localhos

Sorry, I didn't spot the typo.

Im still getting the same error.
The file on my Pi is id_ed25519.pub so thats what I used. ( I tried id-ed25519.pub but it doesn't find the file).

Do you actually have an authorized_keys file and if you do is it empty? Or does it have keys you don't need to keep in there?

And have you actually generated a key pair for that user on the Pi? If you haven't $HOME/.ssh let alone $HOME/.ssh/authorized_keys won't yet exist.

It's just a text file so you could try the following:

1. If required, backup any existing $HOME/.ssh/authorized_keys file.

2. Code:

   cd

   to get back to your home directory, assuming that's where your key file is.

3. Code:

   mv id_ed25519.pub .ssh/authorized_keys

   mv is move but you could use cp (copy) if you prefer.

4. Code:

   chmod 644 .ssh/authorized_keys

   Makes sure only the owner can write to it. If others can ssh won't use it.
