The installation process was killed while trying to overwrite something that was left by a previous installation. My advice:
[]Stop any mysql service
]Kill any existing mysqld_safe and mysqld process
[]Run apt-get purge mariadb (and MySQL and whatever was previously installed)
]Remove any directory created by those packages, if it wasn’t removed when you uninstalled them
[]Remove any previous configuration file, especially if it specifies non-standard paths
]Remove mysql group and user
[*]apt-get clean
