Get the link to the latest Antragsgrün release .tar.bz2 release archive, then cd to your document root, download the archive and extract it on the fly, omitting the top-level directory from the archive:

[isabell@stardust ~]$ cd html
[isabell@stardust html]$ rm nocontent.html
[isabell@stardust html]$ curl -L | tar -xjf - --strip-components=1

Create the database

First, create a MySQL database to hold your Antragsgrün installation

[isabell@stardust html]$ mysql --verbose --execute="CREATE DATABASE ${USER}_antragsgruen"
CREATE DATABASE isabell_antragsgruen
[isabell@stardust html]$

Web installer

You can now head over to your web site and complete the web installer. Use localhost as your database server, the name of database you created in the previous step (isabell_antragsgruen in our example) and your personal MySQL password.


Use the built-in web updater.

Tested with Antragsgrün 4.10.1, Uberspace 7.13.0, and PHP 8.1
