Well, that didn’t go well. I skipped reading the ReadMe on upgrading to Fedora 36 on Moodle.org and after upgrading I realized I was on PHP 8.1 and Moodle doesn’t run on that version. I followed these instructions https://computingforgeeks.com/how-to-install-php-on-fedora/ to install the REMI repository and then PHP 8.0. I did get into some particulars with ensuring that the zip library was installed as different versions report back different entities. In the end it all sorted out and while I don’t have a lovable generic Fedora install I at least have Moodle 4.0 back up and running in time for the school year.
