Web page 404 error on LAMP stack on Ubuntu 18.04 GitHub-hosted Runner for GitHub Actions

Question

For some reason, I can access the homepage of my site (there's an index.php) but every other page gives a 404 error. The PHP framework used is Joomla CMS. I have in my .htaccess file the following line AddHandler application/x-httpd-php7 .php. Everything is via HTTPS. I tried to access via curl and Python Selenium. Both give the same problem. Note that in my development environment (local Windows 10) and in production (Linux) I have no such problem.

For GitHub Actions workflow, I've setup MySQL using services property in YAML. I made PHP7.4 as the default with command sudo update-alternatives --set php /usr/bin/php7.4. For Apache, these is the step:

- name: Config and start Apache server
run: |
    sudo ufw disable
    sudo touch /etc/apache2/conf-available/ssl-params.conf
    sudo apt install libapache2-mod-php7.4
    sudo a2enmod php7.4 deflate expires filter headers rewrite ssl proxy proxy_http
    sudo a2enconf ssl-params
    sudo a2ensite default-ssl
    sudo systemctl restart apache2
    sudo ln -s /home/runner/work/web/web /var/www/html/mysite

Answer 1

I got it working by updating Apache config with the following workflow step: sudo perl -i -p -e "s/AllowOverride None/AllowOverride All/g" /etc/apache2/apache2.conf
