##Type of keys tried:

• https://docs.gitlab.com/ee/ssh/README.html#ed25519-ssh-keys
• https://docs.gitlab.com/ee/ssh/README.html#rsa-ssh-keys

1. ssh-keygen -t ed25519 -C "" --> same error [cat ~/.ssh/id_ed25519]
2. ssh-keygen -t rsa -b 2048 -C "" --> same error [cat ~/.ssh/id_rsa] The errors are the same for both type of keys.

Notes:

I have also tried cat ~/.ssh/id_ed25519 | tr -d '\n' cat ~/.ssh/id_rsa | tr -d '\n' but no go. I tried copying it from the vi editor. I am extremely appreciative of the product and what it offers to us. I hope to get this solved by knowing what I might be doing wrong or what is wrong here!.
