Почему установка MariaDB длится долго?

Установка mariaDB длилась долгое время, завершая процесс терминала.

$ sudo apt-get install mariadb-server mariadb-client

Попытка снова установить MariaDB вызвала следующие проблемы:

Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 31891 (apt-get) - open (11: Resource temporarily unavailable)

Итак, я нашел следующее решение.

$ sudo rm /var/lib/apt/lists/lock
$ sudo rm /var/cache/apt/archives/lock
$ sudo rm /var/lib/dpkg/lock*

$ sudo dpkg --configure -a
$ sudo apt update

Но это также вызвало некоторую проблему:

$ sudo dpkg --configure -a

Я удалил и переустановил MariaDB, но установка долго не завершалась.
