проблема с установкой MySQL на Ubuntu 15.04

При попытке выполнить следующее:

apt-get install mysql-server mysql-client

Я получаю следующий ответ:

debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline

Я выполняю роль root.

Кто-нибудь знает, как это исправить? Я новичок в этом. Я нашел несколько похожих сообщений на этом сайте, но просто не могу найти решение.
