Isso parece muito complicado. Tente usar o seguinte em localhost :
scp ~/.ssh/id_rsa.pub [remotename]@[remote.com]:.ssh/uploaded_key.pub
Estou tentando copiar uma chave pública para um servidor remoto. Estou logado localmente como [nome do local] e a chave reside localmente em ~/.ssh/ . Eu também sou ssh em [remote.com] como [remotename], e tentando enviar a chave assim:
scp [localname]@localhost:~/.ssh/id_rsa.pub [remotename]@[remote.com]:/home/[remotename]/.ssh/uploaded_key.pub
Eu vejo a mensagem de boas-vindas para [remote.com], mas me perguntam:
[localuser]@localhost's password:
Mas a senha do [localuser] (a que o [usuário local] usa para fazer login na máquina local) não é aceita:
Permission denied, please try again.
Aqui está a saída detalhada:

Alguém pode verificar se esse é o uso correto do scp ou oferece dicas para solução de problemas?

Pergunta interessante, eu apenas tentei a mesma coisa e me deparei com o mesmo bug. Eu usei a opção -vvv para descobrir o que está acontecendo sob o capô e basicamente é ssh para seu host local e executa scp -v ~/.ssh/id_rsa.pub remoteuser@remoteserver:~/
Isso deve funcionar bem, no entanto, o comando tenta ler a senha de stdin, mas sem controlar tty, não há senha, portanto, a permissão negou mensagens.
Aqui está uma versão reduzida da depuração, o que explica o meu ponto:

debug3: remaining preferred: ,password

debug1: Next authentication method: password
dpac@localhost's password:

Não encontrei até o momento scp versão que suporte a especificação "remota" para origem E destino.
