I just had to setup a new machine, and new ssh keys.
I visited
https://admin.fedoraproject.org/accounts/user/edit/xxxx
I chose my new id_rsa.pub to upload.
But I get:
git push --verbose
Pushing to ssh://nbecker@pkgs.fedoraproject.org/mercurial
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
Hints?
