As it stands this is unlikely to be changed. By default universe is
enabled. This can be verified or added with the following command:
sudo add-apt-repository universe
Output:
'universe' distribution component is already enabled for all sources.

Title:
SRU: Default dependency resolution in Focal pulls in full GNOME

Bug description:
In Bionic, screen-resolution-extra has a dependency on
policykit-1-gnome | polkit-1-auth-agent. Focal replaces this with a
dependency on gnome-shell | policykit-1-gnome | polkit-1-auth-agent.
As a result, when install screen-resolution-extra (e.g. as a
dependency of nvidia-settings) on a system that doesn't already have
GNOME or another polkit auth agent installed, the default dependency
resolution pulls in a full GNOME desktop in Focal, while it does not
do so under the same circumstances in Bionic. This can be worked
around by explicitly installing policykit-1-gnome (or another package
which provides the polkit-1-auth-agent virtual package), but it would
be nice to not pull in GNOME by default on a system that doesn't
already have it.
[Impact]
* Installing the nvidia-settings package causes gnome-shell to be
installed. This is less than ideal on servers.
[Fix]
* Moving policykit-1-gnome ahead as the first of the polkit
dependencies will solve the problem.
[Test Case]
* Install screen-resolution-extra from proposed on a system where no
polkit-1-auth-agent provider is installed, and check that gnome-shell
is not installed as a dependency.
[Regression Risk]
Low, as the change will still allow the dependency to be satisfied.
