<html><body>I forgot to mention the exact GRUB versions:<br><br>- My Debian 10.13 Netinst based installer had GRUB: 2.06-3~deb10u1<br>- My Debian 10 based installed system had GRUB: 2.06-3~deb10u4<br>- My Debian 11.9 Netinst based installer had GRUB: 2.06-3~deb11u6<br>- My Debian 11 based installed system had GRUB: 2.06-3~deb11u6<br><br>Now, I also tested with a Debian 12.5 Netinst based installer that had GRUB 2.06-13+deb12u1. My script printed some errors and warnings while generating that installer, but the installer worked good enough to confirm that this bug also affects the Debian 12 installer. I did not test the Debian 12 installed system (but I guess it could be unaffected like my Debian 10 and 11 installed systems).</body></html>
