Current Behavior

Error:

SSH should work

[thespad]

config/.ssh/id_ed25519.pub is not /config/.ssh/id_ed25519.pub

[aptalca]

PUBLIC_KEY_FILE=config/.ssh/id_ed25519.pub is incorrect. Needs to be the internal path

[katelovescode]

config/.ssh/id_ed25519.pub is not /config/.ssh/id_ed25519.pub

@thespad and @aptalca , thanks, this fixed it.
