I am trying to install Xibo Docker on a clean Ubuntu VPS, but the cms-web container seems to be empty. The /var/www/html directory does not contain a composer.json file, making the installation impossible.
Hi GALERIA_DE_QUEBRADA, welcome to the Xibo community!
Have you been following the steps in the Docker based installation guide? You should be able to download the pre-configured containers for the current latest release (4.2.3 at the time of writing this) from this link.
The installation document suggests creating a directory for your install in a suitable location on your Linux machine. Typically we recommend /opt/xibo as the directory you should use. You shouldn’t need to access /var/www/html for the setup of your CMS.
