I recently updated my Debian desktop to Trixie. It went fine but Grub broke. It got as far as "Welcome to GRUB" then black screen and reboot.
I fixed that by doing grub-install and update-grub in a chroot but what went wrong and can I avoid this annoyance in the future? Is this a known problem? I remember seeing an off hand mention that this "often" happens on Debian and derivatives but didn't pursue it then and don't have a reference. And it's never happened to me before.
