The package that is causing the problem is: linux-firmware
What I did was place a hold on that package so that Apt Package Manager will not try and update it.
Here is what I did for my testing.
hive-replace -y --stable
apt-mark hold linux-firmware (You can remove later with the unhold command)
apt-get install nvidia-settings xserver-xorg-core
Later on if you want to see what packages you have on hold:
Remove from hold:
apt-mark unhold linux-firmware
I am not sure what was inserted into the linux-firmware package, but when Ubuntu replaces it with the newer version the Temps/Powers/Fan reporting stops working after reboot. Hope this saves someone else some time. Obviously it would be nice to update the linux-firmware as it is updated, but maybe HiveOS can tell us how to run a command to insert the code needed, or a process to restore that version if it ever gets replaced.
