Alpine Linux: фатальный: privsep_preauth: дочерний элемент preauth завершен сигналом 31

У меня есть несколько контейнеров с Alpine Linux. Вчера я обновил два из них с v3.8 до v3.10. Сервер OpenSSH был обновлен с 7.7_p1-r4 до 8.0_p1-r0 . После этого клиент не может войти в систему.

Примечание: при использовании конфигурации sshd по умолчанию, ничего не редактировалось.

Это журнал клиента:

Я видел несколько похожих отчетов об ошибках, но большинство из них довольно старые . В некоторых сообщениях предлагается добавить параметр UsePrivilegeSeparation , но он устарел . Если я вернусь к использованию версии 7.7 , установив репозиторий 3.8 и удалив / установив openssh, все будет работать нормально.

Поскольку я буду продолжать обновлять контейнеры, я хотел бы знать, что я могу сделать, чтобы исправить этот выпуск.
