When installing update, response comes back:

Check if you are using third party repositories. If so disable them, since they are a common source of problems.

Furthermore run the following command in a Terminal: apt-get install -f

Transaction failed: The package system is broken

 The following packages have unmet dependencies:



libglx-mesa0: Depends: libglapi-mesa (= 18.0.5-0ubuntu0~18.04.1) but 18.2.2-0ubuntu1~18.04.1 is installed

nothing else is running (no, no X11 either)---

lsmod | grep nvidia.drm returns 

nvidia_drm             40960  2

nvidia_modeset       1089536  2 nvidia_drm

drm_kms_helper        172032  2 nvidia_drm,i915

drm                   401408  16 drm_kms_helper,nvidia_drm,i915

sudo modprobe -rf nvidia_drm seems to work as does
sudo modprobe -rf nvidia_modeset

However, lsmod | grep nvidia.drm shows them to still be there

sudo modprobe -rf drm_kms_helper yields

modprobe: FATAL: Module drm is in use.

same with

sudo modprobe -rf drm

an attempt to upgrade the Nvidia driver to the latest (download and run) gives:

ERROR: An NVIDIA kernel module 'nvidia-drm' appears to already be loaded in your kernel.  This may be because it is in use (for  

         example, by an X server, a CUDA program, or the NVIDIA Persistence Daemon), but this may also happen if your kernel was   

         configured without support for module unloading.  Please be sure to exit any programs that may be using the GPU(s) before 

         attempting to upgrade your driver.  If no GPU-based programs are running, you know that your kernel supports module       

         unloading, and you still receive this message, then an error may have occured that has corrupted an NVIDIA kernel         

         module's usage count, for which the simplest remedy is to reboot your computer

switching to su, I ran

systemctl isolate multi-user.target

which killed the computer, and upon reload, same problem

I'm at an impass... ANYONE???
