SSH:Generate Key
If you will receive an error saying “No such file or directory” then, it means you don’t have an SSH key on your machine. So, move to the next step. Generate the SSH key pair on the Ubuntu client machine. To generate a new 4096 bits key pair with a user email address as a comment, execute the following command:
ssh-keygen -t rsa -b 4096 -C "user@email.com"
Or
ssh-keygen
If you run the above command “ssh-keygen”, it generates a default 3072-bit RSA key pair. To save the SSH key on the default location in the ‘.ssh/ ’ sub-directory, hit ‘Enter’.
