GitLab SSH Keys - В доступе отказано (publickey)

Я следовал этому документу, чтобы настроить мою аутентификацию SSH https://kgcoe -git.rit.edu / help / ssh / README # generation-a-new-ssh-key-pair

Раньше это работало, но на этот раз при новой установке я получаю Permission denied (publickey) ошибка

Ниже приведен отладочный вывод команды ssh

Команда: 

sudo ssh -vT git@pc3.instageni.utc.edu

работает от имени пользователя root и будет использовать /root/.ssh/config и закрытый ключ ssh из того же каталога, например /root/.ssh/id_rsa. В команде: 

sudo ls ~/.ssh/

оболочка, вероятно bash, расширится ~ до вашего домашнего каталога до того, как она даже вызовет sudo (докажите это sudo echo ~), поэтому она будет отображать файлы из вашего дома каталог, вероятно /home/ankushko.

Могу я спросить, почему вы запускаете эту команду с sudo? Будет ли работать просто подключиться как обычный пользователь? Это было бы более безопасно, но иногда нужно запускать все с правами root.

В любом случае вам необходимо убедиться, что используемый вами личный закрытый ключ ssh совпадает с публичным ключом ssh на сервере.
