A few days ago I tried installing Debian testing on my laptop using the then most recent official testing netboot image (20241203). I tried several times with or without the graphical installer. Each time I ended up with the error that the installer can't find a kernel to install.
It offers to install without a kernel but an other user who actually tried that ended up with an error he couldn't recover from later. We discussed the issue in the Debian forum: https://forums.debian.net/viewtopic.php?p=812436#p812436 What are we doing wrong?
