I am installing a LEMP stack on a fresh minimal install of Ubuntu 14.04 LTS.

When I tried to install MySql

sudo apt-get install mysql-server

it returned an error with the following explanation:

mysql-server depends on mysql-server-5.5; however:
Package mysql-server-5.5 is not configured yet.

How do I solve this problem?

What I have read

This question is very similar to Upgrade MySQL server issue, however, that question was (incorrectly, I believe) marked as a duplicate of this question. None of the answers to these two questions solved my problem.

I have also seen E: Mysql-server-5.5 Installation Error. This question was closed for being unreproducible. However, I can reproduce my problem every time I try to install mysql server on a fresh minimal installation of Ubuntu 14.04 (the key word being minimal).

Purpose of this question

I finally solved my problem, but I could not add an answer to any of the questions I linked to above, so I am creating a new question here so that I can answer it myself.

The main problem is that the minimal Ubuntu install does not have everything that you need.

The post Package mysql-server-5.5 is not configured yet provides the solution to your problem. I suggest you read that. However, I will provide a brief summary below.

Clean out the old mysql installation.

sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean

Upgrade the things that are missing in the minimal Ubuntu installation.

sudo apt-get dist-upgrade

Install MySql as normal:

sudo apt-get install mysql-server

If that still doesn't work you can do

 sudo apt-get install mysql-server --fix-missing --fix-broken
