Bug#1107788: Release candidate kernels are sorted before released kernels

Vincent Bernat Sat, 14 Jun 2025 10:57:31 -0700

Package: grub-common
Version: 2.12-8
Severity: normal
Tags: patch upstream


Hey!

When there is a RC kernel, it is booted instead of the more recentreleased one.


 19:53 ❱ ls /boot/vmlinuz*
/boot/vmlinuz-6.15-amd64  /boot/vmlinuz-6.15-rc7-amd64

Attached a patch to fix this issue.
