полез разбирать что такое линукс и с чем его едят. Так вот.
Создал я отдельного юзера под это дело, сделал ему свой ssh, после чего подключил к GitHub для выполнения actions.
Вопрос:
actions отрабатывают корректно, с GitHub к впс подключиться удаётся, а вот если "пингануть" GitHub из впс через ssh -T git@github.com, то я получаю ошибку. Почему так?
