I was redirected here from:
https://pagure.io/fedora-infrastructure/issue/12460
to sum up, I have uploaded my SSH key to pagure, but I still see the error:
"You need to upload SSH key to be able to clone over SSH." on the website
It works in terminal when I type "fedpkg clone forks//rpms/". or "git clone ssh://ndavidov@pkgs.fedoraproject.org/forks/ndavidov/rpms/pgbadger".
The image and the conversation is in the link.
