`dnf` doesn't install suggested anymore?

Which kind of dependencies (suggested, recommended…) does DNF install? says suggested packages should be installed by default.

~ cat /etc/dnf/dnf.conf 
# see `man dnf.conf` for defaults and possible options

[main]
gpgcheck=True
installonly_limit=3
clean_requirements_on_remove=True
best=False
skip_if_unavailable=True

So when installing neovim, dnf should fetch python3-neovim as well.

~ sudo dnf repoquery --tree --suggests neovim

neovim-0:0.7.0-1.fc36.x86_64
 \_ python3-neovim-0:0.4.3-4.fc36.noarch [4: python3.10dist(greenlet), neovim, python(abi) = 3.10, python3.10dist(msgpack) >= 0.5]
neovim-0:0.6.1-3.fc36.x86_64

But that doesn’t happen.

~ sudo dnf info python3-neovim --installed   
Error: No matching Packages to list
~ sudo dnf install neovim

Recommends / Supplements are considered weak dependencies.

Suggests / Enhances are hint.

So the answer given by @ankursinha is wrong.

dnf by default installs weak-Recommends: dependencies, and ignores weak-Suggests:.

neovim starts with some not very clear errors if python3-neovim (which is ignored suggested) is not installed. Docs could also explain how to actually trigger dnf to install suggested.

No, that post is correct. The documentation is a bit confusing.

The definition at the beginning includes

They come in two strengths: “weak” and “hint”

Then later

Hints are by default ignored by dnf. They may be used by GUI tools to offer add-on packages that are not installed by default but might be useful in combination with the installed packages. The requirements of the main use cases of a package should not merely be referenced by hints but included by strong or weak dependencies.

neovim starts with some not very clear errors if python3-neovim (which is ignored suggested) is not installed.

Please file a bug for this, How to file a bug :: Fedora Docs

Thanks.

I am tired of filling bugs. I guess the ratio of positive feedback from this activity is much lower than the noise I get about bugs that will be closed with no attention because the new Fedora is released. The reporting process could also be automated with tools likeubuntu-bug or reportbug - Debian Wiki but it is still a manual process.

In that context the documentation is wrong then to define hint dependencies as weak dependencies.
