Dear Maintainer,
At the end of the Debian installation, the installation of the Grub package >fails.
I first found this bug with the Debian 12.0 installer in september, but it is >still present in 12.4. My goal is to install a Debian with full disk >encryption, I just let the Debian Installer configure everything to use my >whole disk and create needed partitions. The installation performs well, but at
the end Grub is not installed. I got the message "Unable to install GRUB into >dummy". You can see in this capture the whole error messages: >https://pic.infini.fr/gallery#0aTFatc6/ALzRXAY9.png
I tried an installation without encryption and get the same error. I got this >error with Linux Mint too, but I managed to repair Grub after the installation >(only /home encryption). I did not manage to repair GRUB manually with Debian >and full disk encryption, and I didn't try without the encryption.
The PC is an Asus Expertbook B9400C. The BIOS is up to date (2023-12-12) and it
can only boot on EFI. The SSD is in GPT mode and all partitions were made using
the "automatic" mode. I used a USB drive made by the Linux Mint tool (which is >basically a GUI for dd).
