I installed Moodle accordint to the following web site
https://docs.moodle.org/401/en/Step-by-step_Installation_Guide_for_Ubuntu
Ubuntu Version 20.04
Moodle Version 4.0.5 (MOODLE_400_STABLE)
PHP Version : PHP 8.1.13 (cli) (built: Nov 26 2022 14:07:36) (NTS)
Mysql Version: mysql Ver 8.0.31-0ubuntu0.20.04.2 for Linux on x86_64 ((Ubuntu))
Everything worked fine until the Add user option. On reaching that page, the following error message is displayed
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I tried several times to install moodle by deleting the moodle database and moodledata directory, but the result was the same.
