My Error im getting when trying to Connect is
Failed to Connect to host | ssh: handshake failed: knownhosts: key is unknown
#Golang Connect to SSH Server & Accept Host automatically
light spoke
spring dome
so you know this is a bad idea, man in the middle etc etc right ?
so figuring out a prompt to give the user is a much much better solution
but if you simply cannot, I can find this one solution but it involves a key https://skarlso.github.io/2019/02/17/go-ssh-with-host-key-verification/
keys are generally better practice if you can use them, harder to break than easy to remember passwords
if you have access to the command line there are various ways to add the new known host
