Black screen after package upgrade (a311D)

See this post and my follow-up to it:

Display driver issue?

I’ve run into this problem as well. I can’t update my kernel as the linux-image-6.12.5-mnt-reform-arm64 package in the mnt repo has been renamed to .deb.off so I get a 404 when trying to apt upgrade. I’m not familiar enough with apt to know what to do here. I have linux 6.8.11 packages still installed from the last time I did an upgrade. Is there a way to get apt to swap back to that older kernel?

With the default MNT repo you cannot currently upgrade to the faulty kernel version. If you try, you will just get a 404 as Lukas renamed the broken kernel by adding the .off suffix.

Currently, I only know of myself and @ephase who experienced this issue on their A311D classic Reforms. If you really want to have kernel 6.12, then you can test kernel I built using the MNT gitlab CI using the information from my post above.
