Ubuntu 18.04 freezes frequently and sudo ubuntu-drivers autoinstall does not work

Question

I noticed how my Computer starts to freeze more often, which concerns me. I have a Ubuntu 18.04 and it freezes completely so that I have to reboot it.

I ran "ubuntu-drivers devices" since I read online it could be a graphics issue.

ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:03.0/0000:05:00.0 ==
modalias : pci:v000010DEd00000FFDsv0000103Csd00000967bc03sc00i00
vendor   : NVIDIA Corporation
model    : GK107 [NVS 510]
driver   : nvidia-340 - distro non-free
driver   : nvidia-driver-390 - distro non-free recommended
driver   : xserver-xorg-video-nouveau - distro free builtin

Because of the recommendation I tried to install nvidia-driver-390 and it did not work:

sudo ubuntu-drivers autoinstall

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:

The following packages have unmet dependencies:
 nvidia-driver-390 : Depends: xserver-xorg-video-nvidia-390 (= 390.48-0ubuntu3) but it is not going to be installed
                     Recommends: libnvidia-compute-390:i386 (= 390.48-0ubuntu3)
                     Recommends: libnvidia-decode-390:i386 (= 390.48-0ubuntu3)

E: Unable to correct problems, you have held broken packages.

To fix this I ran:

sudo dpkg --configure -a && sudo apt update --fix-missing && sudo apt install -f && sudo apt full-upgrade

but I still get the same error message when I try to install nivida-driver-390

What could I try next?

edit: things that were asked for in the comments:

apt-cache policy nvidia-driver-390
nvidia-driver-390:
  Installed: (none)
  Candidate: 390.48-0ubuntu3
  Version table:
     390.48-0ubuntu3 500
        500 http://archive.ubuntu.com/ubuntu bionic/restricted amd64 Packages

grep "bionic-updates\|bionic-security" /etc/apt/sources.list
(returns nothing)

after running the lines suggested by mchid in the answer:

Answer 1

It seems you are missing the following lines from your /etc/apt/sources.list file:

deb http://security.ubuntu.com/ubuntu bionic-security main restricted
deb http://archive.ubuntu.com/ubuntu bionic-updates main restricted

You will need to edit your /etc/apt/sources.list file but first, run the following command to make a backup of the file:

sudo cp /etc/apt/sources.list /etc/apt/sourceslist

Now, run the following command which will edit your file and add the missing lines:

printf '\ndeb http://security.ubuntu.com/ubuntu bionic-security main restricted\ndeb http://archive.ubuntu.com/ubuntu bionic-updates main restricted\n' | sudo tee -a /etc/apt/sources.list

Finally, run the following commands to update your package list and install the nvidia driver:

sudo apt update
sudo ubuntu-drivers autoinstall

Also, you should probably run a full upgrade as you are most likely missing other updates:

sudo apt full-upgrade

Please post any errors.

Answer 2

Try Install xserver-xorg-video-nvidia-390(With Apt). If a different version is installed, uninstall it and then try sudo ubuntu-drivers autoinstall again.
