Ошибка при попытке установить mysql сервер

Я недавно попытался установить сервер MySQL, но я застреваю с этой ошибкой:

E: Подпроцесс/usr/bin/dpkg возвратил код ошибки (1)

Это - то, что я пытался сделать для установки сервера MySQL:

sudo apt-get install mysql-server

но после ввода этой команды я получил эту ошибку:

dev@webos-develop:/var/lib/dpkg/info$ sudo apt-get install mysql-
server
