I am trying to use backported kernel versions 6.5 and 6.7 on Debian 12. Despite following the official instructions for setting up the Debian backports repository and updating APT's cache, I am only able to access the latest 6.9.x backported kernel version. Specific kernel versions 6.5 and 6.7 are not available in the current backports repository.
Here’s what I have done so far:
1. Added the Backports Repository:
