Hi, I'm emailing this list because I didn't know a more specific place to report this bug. What I Did -------------- - I used GNOME Boxes 42 (from my Ubuntu 22.04 LTS host). - I clicked + then Download an Operating System and chose Debian Testing. - I believe this uses https://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/debian-testing-amd64-DVD-1.iso and https://salsa.debian.org/libvirt-team/osinfo-db/-/blob/debian/sid/data/install-script/debian.org/debian-preseed-desktop.xml.in - I increased the virtual disk size a bit on the confirm prompt (to like 25 GB) - That install worked and I got a functioning Debian GNOME Testing install. - Then I used today's daily build of Ubuntu 22.04 (pre-release) to install Ubuntu. - It resized the Debian partition and I had to manually tweak it just a bit to get a big enough partition for Ubuntu alongside Debian. - After installing Ubuntu, there was a Debian option in the grub boot menu installed by Ubuntu. - Debian failed to boot. I'm attaching a screenshot. It says: error: bad shim signature. error: you need to load the kernel first. Maybe this is as easy as telling osinfo-db to also install a signed kernel. Maybe the signing thing is more complicated. I'm not really going to spend more time on this issue but I wanted to pass it along so that someone else who is interested could try to fix it. Thank you, Jeremy Bicha
