Пакеты Ubuntu не обновляются

Я получаю этот вывод:

7 packages can be updated.
7 updates are security updates.

всякий раз, когда я подключаюсь к своему серверу. и я все еще вижу, что эти пакеты не обновлены! И я root (sudo su).

Когда я sudo apt-get update получаю это:

myserver@YHserver:~$ apt-get update

, что мне делать, чтобы обновить его? Это обновление для системы безопасности и кажется важным

Я всегда запускаю apt-get upgrade -y после «обновления».

Я НЕ удалял файл блокировки и следил за вторым комментарием к этому сообщению: Не удалось заблокировать каталог администрирования (/ var / lib / dpkg /) - это другой процесс с его использованием? И это не помогает. Я не вижу процесса, который держит «apt»
