Install Latest Nvidia Drivers: unmet dependencies

Question

Few months ago, I updated the system from 16.04 to 18.04 with sudo do-release-upgrade. Many things broke I wasn't able to login with Nvidia Driver, etc but somehow managed to get things working.

However now when I try to update the GPU driver with sudo ubuntu-drivers autoinstall I get the following issue:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

I am not knowledgeable about the package manager and would really appreciate some help!

Note: I tried manually installing the recommended package but the package manager was removing tons of installed package which got me worried. So i cancelled the install.

If you have a previous NVIDIA driver installed, you need to remove that one prior to installing the next version. — Terrance, Apr 16 '20 at 14:11
@Terrance Thanks for the reply. It was removing various packages not just the drivers. I will update the question with the same. — CodeCollector, Apr 16 '20 at 14:14
So basically what I am seeing there is that you probably installed CUDA first and it installed the NVIDIA drivers along with it. That is usually what causes that. is this what you are getting when you run sudo apt remove nvidia-driver-418? — Terrance, Apr 16 '20 at 14:24
If I remember correctly, that is what i got when i tried sudo apt install libnvidia-common-440 libnvidia-compute-440 libnvidia-fbc1-440 nvidia-utils-440 . To meet the unmet dependencies I tried to install them manually. — CodeCollector, Apr 16 '20 at 14:30
If you install nvidia-driver-440 it should automatically grab all its dependencies and install them automatically so there should be no reason to install those one by one. That is given you are using the graphics-drivers PPA. Try just running the apt remove nvidia-driver-418 and see if it gives you the same output of all those apps wanting to be removed. — Terrance, Apr 16 '20 at 14:32
Running apt remove nvidia-driver-418 only leads to
The following packages will be REMOVED: cuda cuda-10-1 cuda-demo-suite-10-1 cuda-drivers cuda-runtime-10-1 nvidia-driver-418 0 upgraded, 0 newly installed, 6 to remove and 0 not upgraded. After this operation, 12.3 MB disk space will be freed.

Post which I should try installing nvidia-driver-440 right? — CodeCollector, Apr 16 '20 at 14:35
Are you using CUDA? If not, you can run that as sudo apt remove --autoremove nvidia-driver-418 to remove the previous version. Then run sudo apt install nvidia-driver-440 to install the newest version. After the install you will have to reboot. The reason why you can't install the other 440 apps is that the 418's are still there and conflict with the newer versions. — Terrance, Apr 16 '20 at 14:37
See: https://askubuntu.com/a/1077063/231142 and about 1/2 way down you will find the .run file install and there you will see that you can install CUDA separately than the NVIDIA driver, if you are using it that is. — Terrance, Apr 16 '20 at 14:40
Yes I need CUDA as many of the projects have it as a dependencies. However I understand what you said. Thank You very much. I'll try removing the previous driver and then updating to new one. Thank You. — CodeCollector, Apr 16 '20 at 14:40
I did try to install from run-file but I was getting some error regarding unloading of the previous driver. Will go through the shared link. Thanks. — CodeCollector, Apr 16 '20 at 14:42
It looks to me that the 418 driver was installed by the CUDA installation itself. That is why in my instructions I state to unselect that driver that way you can use any of those NVIDIA drivers you want. =) I hope it all works for you! — Terrance, Apr 16 '20 at 14:43
Just went through this on 20.04. Another trick is to copy the ...cuda location, let the autoremove delete all those cuda files, then restore the copy. This removes the CUDA deb from the package manager, lets you install/maintain the latest nvidia drivers, and works fine with DNN, Tensorflow. Since all your cuda files (and gcc links to old versions) are in cuda/bin, nothing really needs to be in a system location to run CUDA. — ubfan1, Apr 16 '20 at 16:14

I just dealt with the same issue on Kubuntu 20.04 when trying to install nvidia-driver-465.

My active driver was 460, so I checked to see what other drivers were installed.

From an Ubuntu 18.04 with current Nvidia drivers (435 or 440 depending upon kernel, no graphics-drivers ppa needed), the problem described is caused by installing a CUDA deb file with an old Nvidia 418 driver (right in the package name).
This removes (but not purges) the Nvidia 440, and a simple reinstall attempt of the 440 will fail with the above noted errors on missing dependencies.

You can put the nvida-driver-435 and all the missing dependencies on one line: sudo apt-get install nvidia-driver-440 libnvidia-gl-440 etc.) and the 440 driver will get installed.
When the 418 driver is removed, you will be notified about all the Cuda debs dependent upon it, and are now subject to autoremoval. This is actually a runnable state, but you really do not want a random autoremove deleting all your CUDA files.
1. Before you do the autoremove, just copy the whole cuda directory that was installed. Use a copy that preserves links.
2. Then, autoremove, which cleans up the package info, getting rid of all CUDA packages, and copy the CUDA directory back (or just mv it if you don't want to keep it as a backup).

You now have a CUDA installation not tied to the package system, so don't expect any updates. Maybe that's good, given how tightly tied to versions other things like DNN and Tensorflow are.

Having just gone through this on 20.04B, I thought using the .run file might avoid these problems, and allow skipping the Nvidia driver mess.

There are other CUDA packages which do not contain the Nvidia drivers. Look for the entire list of .deb files, and maybe a top level one (which pulls in all the others) will work. There are such debs without "nvidia" in their names, so I'd think that should work.

I can understand why Nvidia did this, that's what they built and tested, and really don't want to spend any effort supporting untested configurations, but CUDA is just an app, which may be installed by a user without touching any system files.

I think the older CUDA versions just had files in their top level deb, so a simple extract, and change PATH and LD_LIBRARY_PATH works.
