Ubuntu Server - после перезагрузки ключ всегда отказывался, до входа в систему [дубликат]

Права на сервере выставлены правильно (чиби). Если у меня нет существующего сеанса ssh, открытого для сервера, то для всех новых сеансов требуется пароль. Однако, если он уже открыт, дополнительные сеансы ssh правильно аутентифицируются с помощью pubkey.

Мой $ дом находится на SD-карте. Я переместил authorized_keys в / и связал его, но это не решило проблему.

Нет открытых сеансов:
