I am trying to install Core 20 on RPi4 and cannot get past the email address for my account. If I go to the Ubuntu page to define the ssh keys, it says to use the keys already defined. It does not say how or what OS to generate them on. Is there a way to generate the keys in Windows and enable them in Ubuntu SSH keys page?
Alternatively, is there a way to avoid this unnecessary linkage to ubuntu.com just to run the OS?
I have created two RSA keys using PuTTYgen and ssh-keygen but neither of them worked on the SSH keys page (reference "official tutorial" above, step 5, item #3) login.ubuntu.com/ssh-keys.
Here's the error message I get when attempting to use those keys:
Note: Only SSH v2 keys are supported.
Public SSH Key: Invalid SSH key data: 'c:/users/fgould/.ssh/id_rsa.pub'
