Unable to import SSH key

[Jonathan Tran]

I'm trying to import an SSH key to use with Ubuntu Core but when I paste my public key, I get the following message

Invalid SSH key data: '<contents of id_rsa.pub>'

I see you have elided the contents of your id_rsa.pub, but on the original report you had shown something similar to this:

Invalid SSH key data: 'ssh-rsa SOME_BASE_64_PAYLOAD'

The problem I think I see is that this is missing one component/comment at the end. Something like this works:

ssh-rsa SOME_BASE_64_PAYLOAD some-identifier

now - a key with no comment is valid generally, but Launchpad/SSO does require it. Note that a comment-less key has to be generated with ssh-keygen -C '' (explicit empty comment), so it's not very common.

You can just append an arbitrary identifier to the end to conform to the expected format.
