Unable to install MySQL on Ubuntu 14.04.2 LTS

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?

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.
