Hello all,

I have looked around for an answer but was unable to find one, and was hoping 
that someone here could help me. *First, some background to my information 
about my question*. I recently ran

apt full-upgrade

on my Debian bookworm system. Because of what seems like a bug in dkms, the 
upgrade to linux-image-6.1.0-12-amd64 could not complete. Running

apt -f install

does not help. The uphshot is that, although I can still boot into my laptop 
using the old version of my kernel (either linux-image-6.1.0-11-amd64 or 
linux-image-6.1.0-10-amd64), I can no longer use apt to upgrade other packages 
on my system. Furthermore when I run

needrestart

I am informed that:

The currently running kernel version is 6.1.0-10-amd64 which is not the 
expected kernel version 6.1.0-12-amd64.

*Here is my question: How can I rollback the broken upgrade safely so that I 
can continue to use my system (in particular, apt) normally? Any help anyone 
can provide would be much appreciated.

*Below are some further details. First, here is the result of running apt -f 
install:

Your file "wifi_regd.c" appears to be broken. The version at

https://github.com/RinCat/RTL88x2BU-Linux-Driver/tree/master

had the undeclared REGULATORY_IGNORE_STALE_KICKOFF removed a couple of months 
ago.

Perhaps you need to update the driver source dkms is working with.
(I don't know about, or vouch for, that github, or know anything about the 
AC1200 or its Realtek driver.)
