Installing Moodle on Ubuntu 20.x
The following are steps to install Moodle on Ubuntu 20.x using PHP 7.4. Your versions may differ. Please note that the instructions on Moodle's page ( https://docs.moodle.org/400/en/Step-by-step_Installation_Guide_for_Ubuntu#Step_2:_Install_Apache.2FMySQL.2FPHP ) are NOT correct. There are some substantial errors on that page. They do not tell you to remove php8.1 They tell you to reset the root password using a method that is confusing and causes problems. Their steps for SSL do not work. Rather follow these instructions. 1.

First find out the version: php -v If it returns version higher than 7.4, e.g. version 8.1, you have to remove it. At present, Moodle does NOT like php 8. sudo apt remove php8.1 Now tell it about the older php version repository: sudo add-apt-repository ppa:ondrej
