The message says that the format of the key you’re trying to upload is wrong. Why that is is hard to say without knowing exactly what you’re doing.

OpenSSH stores its public keys in files with a .pub ending, the content is one line of text starting with the algorithm (e.g. “ssh-ed25519”) followed by the base64 encoded public key and (optionally) a comment string identifying the key, e.g.: ssh-ed25519 AAAAC3[...] user@host

HI @ahrumnoh,
have you tried following the step-by-step instructions here generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
and then adding-a-new-ssh-key-to-your-github-account
the key format generated and to be copied will be similar to that described by airtower-luna above
