I have tried to install Wikimedia on Fedora 32 (and 31 too) with MariaDB. , always to stumble on something not working. (close to the end).
Many posted here and there the same difficulties. Fedora/RedHat is a very popular Linux distro, usually very good.
The issue is probably some level of permissions.
The ideal (most simple) way should be # dnf install mediawiki
Or a similar dnf command using "group install" etc...
Could you look at this and at least document a valid manual install, then an properly working package install? (using Fedora package installer dnf).
Thanks for the attention.
