According to the driver manager, you manually installed the NVIDIA drivers (using the run file ad downloaded directly from Nvidia) as opposed to using native Ubuntu packages, is this correct?
If so, then yes, those packages are safe to be removed, they are leftovers from the Nvidia 390 driver, and not being used. Even nvidia-settings packages are not needed as this is included with the self-installed driver. Not sure about nvidia-prime.
If you were running the newer 418 driver, these packages would also not be necessary as they are specific to the driver version 390.

A note to add:

Code:

[I] sudo apt-get upgrade[/I]

.
This is not the correct way to update packages on an Ubuntu system. Use sudo apt full-upgrade. Most of the time, using just upgrade is fine, but often enough not every package will be upgraded if something needs to be removed.
Say LibFoobar1 is replaced by LibFoobar2, and requires LibFoobar1's removal. New versions of Packages that depend on LibFoobar2 won't be installed. This mainly happens with Plasma related upgrades, but can happen elsewhere. May not be causing the issue with the driver packages, but it is better safe to use full-upgrade, as that is what Ubuntu's packaging and dependencies are based on.

From apt's manpage:

Code:

upgrade
upgrade is used to install available upgrades of all packages currently installed on the system from
the sources configured via sources.list(5). New packages will be installed if required to satisfy
dependencies, but existing packages will never be removed. If an upgrade for a package requires the
removal of an installed package the upgrade for this package isn't performed.

full-upgrade 
full-upgrade performs the function of upgrade but will remove currently installed packages if this is
needed to upgrade the system as a whole.

thanks claydoh for getting back to me on this and your clarification on the upgrade process.

According to the driver manager, you manually installed the NVIDIA drivers (using the run file ad downloaded directly from Nvidia) as opposed to using native Ubuntu packages, is this correct?

No, this is not correct (I wouldn't even know how to do that

I simply let the Kubuntu 21.04 installer do what it had to do, and that's it...i'm now terrified

at the thought of removing these packages...and ending up with a broken system (like yesterday)...

what do you think I should do?

**Snowhog** · May 11, 2021, 06:02 AM

For now, just open a Konsole and run: sudo apt update && sudo apt full-upgrade

Compare the results (output) from your earlier post.

they look similar to me - at least the to-be-removed packages are listed:

First off, when using apt or apt-get, using "upgrade" instead of "full-upgrade" is not recommended and was only left in place for compatibility reasons (I read that somewhere). The preferred CLI utility is "pkcon" and has been for some time. I still use "apt full-upgrade" but never "apt upgrade"

As far as the nvidia drivers, that list of files seems incomplete if you're trying to use the nvidia driver. There's no kernel packages, only the supporting packages. A more complete list would look something like:

libcuda1-384libnvidia-cfg1-390
libnvidia-common-390
libnvidia-compute-390
libnvidia-decode-390
libnvidia-encode-390
libnvidia-fbc1-390
libnvidia-gl-390
libnvidia-ifr1-390
linux-modules-nvidia-390-5.8.0-50-generic
linux-modules-nvidia-390-5.8.0-50-lowlatency
linux-modules-nvidia-390-aws
linux-modules-nvidia-390-azure
linux-modules-nvidia-390-gcp
linux-modules-nvidia-390-generic
linux-modules-nvidia-390-generic-hwe-20.04
linux-modules-nvidia-390-generic-hwe-20.04-edge
linux-modules-nvidia-390-lowlatency
linux-modules-nvidia-390-lowlatency-hwe-20.04
linux-modules-nvidia-390-lowlatency-hwe-20.04-edge
linux-modules-nvidia-390-oem
linux-modules-nvidia-390-oem-20.04b
linux-modules-nvidia-390-oem-osp1
linux-modules-nvidia-390-oracle
linux-objects-nvidia-390-5.8.0-50-generic
linux-objects-nvidia-390-5.8.0-50-lowlatency
nvidia-384
nvidia-384-dev
nvidia-compute-utils-390
nvidia-dkms-390
nvidia-driver-390
nvidia-headless-390
nvidia-headless-no-dkms-390
nvidia-kernel-common-390
nvidia-kernel-source-390
nvidia-libopencl1-384
nvidia-opencl-icd-384
nvidia-utils-390
xserver-xorg-video-nvidia-390

Not that you would need all of these but notice you don't have the driver or dkms package in your "autoremove" list. IME, the nvidia driver packages would never be in the autoremove list unless the installation was incomplete.

I suspect either you somehow removed (or never installed) some required packages or you are missing a dependency to use the driver, like the dkms package. If this is so, then you are probably using the nouveau driver. To text this theory, type this into konsole:

lspci -vnn | grep -i VGA -A 12

This should reveal the active driver. Assuming my guess is right, then type:

sudo apt install nvidia-390

and this should install what is needed. My best guess would be you don't have dkms installed.

thank you and please see the output here below. I see "nouveau" in the list, but I also see other terms which I don't understand, I'm afraid. Does the output confirm your suspicion, i.e., would it be enough that run

sudo apt install nvidia-390

and would this command also install "dkms"?

Ideally, the Kubuntu install should have the packages it needs and not suggest them for removal, and the other posters are helping you with that.

But, if removing them breaks the system, then they're needed now. Marking them as "manually installed" will stop autoremove removing them; f. ex.

Code:

sudo apt install libnvidia-cfg1-390
