Running Ubuntu 18. Moodle 3.3.5+ (Build: 20180515)
Error - version 5.5.31 is required and you are running 22.214.171.124.1.29.6
Anyone know the Ubuntu commands to update this??
sed -ri -e "s|\\$CFG->dbtype\s*=\s*'[^']+';|\\$CFG->dbtype = 'mariadb';|" /path/to/moodle/config.php
When you have installed Moodle you have selected MySQL instead of MariaDB .
In the nicest way... that is the most geeky answer to that question I have ever seen
