Following the Ubuntu article to install Ruby, Rails, DB etc fails halfway through.

Hello!

Thanks for looking at this.

After going through this article =>
"(h)(t)(t)(p)(s)(:)(/)(/)gorails(.)com/setup/ubuntu/20.04#final-steps"

On the Git configuring step and after I type in "cat ~/.ssh/id_rsa.pub" and put the whole 4 lines that come back as a result to my github account.
I run this => "ssh -T git@github.com" but the message that comes back is this =>

"The authenticity of host 'github.com (12.82.151.5)' can't be established.
ECDSA key fingerprint is SHA256:adslkjalskdaslkjdalka(etc).
Are you sure you want to continue connecting (yes/no/[fingerprint])?"

Don't mind the ip and SHA256 number I changed them for this post cause I am not sure if I should or not so I did.

So I don't get the "Hi excid3! You've successfully authenticated, but GitHub does not provide shell access."
that the article describes.

I have followed the procedure step by step.

Would you know what's wrong? I sm running ubuntu 20.4 Focal

Thanks in advance!

Okay so basically if you see on the above message it asks you to proceed with typing yes or no and I decided to type yes basically and it now send the right message.

I guess I should have done this before posting on this forum!

Apologies.
