package: calamares version 3.3.1-1
Hi: I attempted to install testing using the Debian live Mate CD. The install completes, however, no boot entry is added to the efi firmware. A partial install of grub is occurring, since the grub files are installed to the efi partition. I tried to determine why the installer isn't creating the entry by examining the log file at /root/.cache/calamares/session.log on the live cd. I can see the grub-install command being run there, however, the output from the command isn't being recorded in the file, and I haven't found this output yet somewhere else to determine why things might be failing. I'll keep looking and update this bug if I find more info on this On systems with secure boot turned off, the system might boot if no other operating system is installed, because the firmware will load the default path /boot/bootx64.efi on one of the disks in the system. I was able to produce this on a system with secure boot turned off (in my case, the installed Debian booted, because my ssd was the only disk in the system). When secure boot is turned on, boot will fail, since no firmware entry has been created pointing to shimx64.efi. I was able to reproduce this failing boot scenario by enabling secure boot. One thing worth noting is that when I boot into the system with secure boot off, and run grub-install, the firmware entry pointing to shimx64.efi is correctly created at that point, so this is definitely a problem in the installer. After installing grub from the installed system, I can then enable secure boot, and boot the installed Debian successfully.
