Hi Sven,thanks for reporting your woes with the Debian Edu 13 main server installation.

Hello,I tried to install Debian Edu 13.1 on a standard VM in Proxmox (KVM, not LXC).The installation stops with the following error from icinga2-ido-mysql: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)At this point in the installer, the database is not running and the socket does not exist. As the error happens during the Debian Edu Installer stage, there is no way to install or start the database manually beforehand.If I press "Retry" in the installer after this error, I get prompted to create the database. Even if I create it, the next step asks whether to use a UNIX or TCP/IP socket for the connection. No matter which option is chosen, the installer ends up in a loop and cannot proceed.The same problem also occurs when installing Debian Edu 13.1 in a VirtualBox VM. When I use Debian Edu 12.7, however, the installation completes successfully in both Proxmox and VirtualBox. So it looks like this is a regression introduced in 13.1 (possibly related to a newer icinga2/dbconfig-common timing issue).Environment: - Proxmox VE: 8.4.9 - VirtualBox: 7.1.6 - Standard VMs (default settings, not containers) - Debian Edu ISO: 13.1 (current release) Questions: 1. Is this a known problem with the 13.1 release?2. Is there a recommended workaround (e.g. avoiding icinga2 DB configuration during installation and re-running later)?Thanks for your work on Debian Edu!
The overall answer is: the main server installation does not yet work and I am focusing on the client installation first. (This seems to work now in all of my customer setups, however, we deploy the clients with debian-edu-fai, so I still need to test D-I).
But I will look into a Debian 13 based Edu main server installation for sure. We need to get this resolved soon.
To set up a school, please use Debian Edu 12 as main server and install Debian Edu 13 clients. To deploy Debian Edu 13 clients, this needs some tweaking of the pxeinstall environment or it requires using debian-edu-fai. Unfortunately, both approaches are underdocumented / documented only in German: https://wiki.it-zukunft-schule.de/Technik/Installation/VM/FAIServer/bullseye (this should mostly work for trixie, too)
That said, any kind of help with maintaining Debian Edu is highly welcome (be it documentation work, development, etc.)
