Topic on Manual talk:Installing MediaWiki

Is there a really easy way to setup and install MediaWiki on an Ubuntu 20.04 server?

Whichever method I follow, there always seems to be something missing, and all that is needed is a foolproof way to do it: from scratch.

See the docs; if it's not "easy" please explain why and ask on Project:Support desk. Thanks!

I have followed the documentation to the letter, and for whatever reason, there seems to be something missing from the instructions since all I get to is a screen that tells me that NGINX is up and running just fine, but needs some modifications: not mentioned in the documentation.

I am not the only one who has hit problems with installing, but as of yet, have not found out what needs to be done to get the thing running properly: really frustrating.

If you get a plain Nginx screen then something needs to be adjusted in your webserver configuration. Is this local or on a publicly-accessible subdomain? Do you have a file like this or this in your sites-enabled?

Hope you found this: Manual:Running_MediaWiki_on_Debian_or_Ubuntu

Make sure you have php-intl installed. I don't think it is optional anymore.
