I just installed Ubuntu 18.04.5 LTS on my workstation along with the recommended nvidia drivers, where I used sudo ubuntu-drivers autoinstall to do so, and ubuntu-drivers devices recommends installing nvidia-driver-450-server - distro non-free recommended.

However, after installing the recommended driver, my package system is broken. When I try to update the software using the "Software updater", I get the following message:

The package system is broken. 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: libnvidia-gl-450: Depends: libnvidia-common-450 but it is not installed
                  Depends: libgcc1 (>= 1:4.2) but 1:8.4.0-1ubuntu1~18.04 is installed
libnvidia-gl-450:i386: Depends: libnvidia-common-450 but it is not installed

A forced installation of the package using sudo apt-get install -f libnvidia-common-450 yields the following error:

dpkg: error processing archive /var/cache/apt/archives/libnvidia-common-450_450.80.02-0ubuntu0.18.04.2_all.deb
(--unpack):
 trying to overwrite '/usr/share/nvidia/nvidia-application-profiles-450.80.02-key-documentation',
 which is also in package libnvidia-common-450-server  450.80.02-0ubuntu0.18.04.3
 Errors were encountered while processing:
 /var/cache/apt/archives/libnvidia-common-450_450.80.02-0ubuntu0.18.04.2_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

And nothing is resolved. Trying to reconfigure the package using sudo dpkg --configure -a says that the package libnvidia-common-450 is not installed. I'm not sure where to go next, and any advice would be greatly appreciated.

I solved this issue by using the the following command to reinstall libnvidia-common-450-server:

sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450-server

The problem started after following an online article to install nvidia drivers. This was the error I was getting:

libnvidia-gl-450-server: Depends: libnvidia-common-450-server but it
is not installed Depends: libgcc1 (>= 1:4.2) but
1:8.4.0-1ubuntu1~18.04 is installed libnvidia-gl-450-server:i386:
Depends: libnvidia-common-450-server but it is not installed

    Worked for me, but had to change to sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450. What a lifesaver! – Erasmus Cedernaes Oct 23 '20 at 13:40

    Thank you so much; this worked for me too when I ran sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450. Interesting to learn that it is a bug - but this solution seems to work quite well. Thanks again!! – Kaszt Oct 29 '20 at 16:02

Same issue. Also because of it could not update via Software updater and other issues installing lead to same dependency error. This fixed it for me too:

sudo apt-get -o Dpkg::Options::="--force-overwrite" install -f libnvidia-common-450
