I’m trying to install MySQL on Ubuntu 14.04.2, (Ubuntu Ruby on Rails on 14.04 (Postgres, Nginx, Unicorn) to be specific).

I’m running this command to install -
sudo apt-get install mysql-serve as root

During the installation, I’m encountering this error -

Setting up mysql-server-core-5.5 (5.5.43-0ubuntu0.14.04.1) ...

Any idea what’s going wrong?

  • Did you first perform a

    apt-get update

    in order to update your apt database?

  • yep, I did that. Still getting the same error.

    Don’t know if it helps, but
    I’m running this to remove the current installation -

    sudo apt-get remove --purge mysql-server mysql-client mysql-common
    sudo apt-get autoremove
    sudo apt-get autoclean

    And then installed MySQL using the above mentioned command. Still getting the same issue.

  • you might try removing your install of mysql first:

    sudo apt-get remove mysql-server&&sudo apt-get autoremove

    then reinstall mariadb:

    get the repository for latest mariadb

    sudo apt-get install software-properties-common
    sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db
    sudo add-apt-repository 'deb http://mirror.stshosting.co.uk/mariadb/repo/10.0/ubuntu trusty main'

    install the needed things

    sudo apt-get update&&sudo apt-get upgrade
    sudo apt-get install mariadb-server mariadb-client 
  • Similar issues with mariadb as well. I’m thinking it might be due to the 512mb ram droplet I’m using. Does that make sense?

Okay, so upgrading the droplet to 1gb ram fixed the issue. Most probably, the mysql service was unable to start due to lack of memory. Maria DB reported a lack of memory while installing.
