I have encountered the same problem Ubuntu 18.04 with MariaDb 10.3.13. I found potential solutions at https://mariadb.com/kb/en/library/what-to-do-if-mariadb-doesnt-start/ but so far no luck.

Check the mysql log for the startup sequence. It will show errors there. It’s usually under /var/log/mysql*
