For example, if I initiate installation of the Greek language meta-package, I am prompted to install its dependencies and weak dependencies.

$ LC_ALL=C sudo dnf install langpacks-el

Is this ok [y/N]:

However, if I try manually listing the dependencies, I don't see the weak dependencies. How can I look them up?

Here is what I tried.

$ LC_ALL=C dnf repoquery --depends langpacks-el
Last metadata expiration check: 3:15:20 ago on Sat Sep 25 14:07:02 2021.
$ LC_ALL=C dnf repoquery --depends langpacks-core-el
Last metadata expiration check: 3:15:42 ago on Sat Sep 25 14:07:02 2021.
$ LC_ALL=C dnf repoquery --depends langpacks-core-font-el
Last metadata expiration check: 3:16:08 ago on Sat Sep 25 14:07:02 2021.

According to the manpage:

dnf [options] repoquery [<select-options>] [<query-options>] [<package-file-spec>]

Searches available DNF repositories for selected packages and displays the requested information about them. It is an equivalent of rpm -q for remote repositories.


Display capabilities that the package depends on, enhances, recommends, suggests or supplements.

dnf repoquery --depends prints only forward dependencies (dependencies listed in the langpacks-el package as Requires/Recommends/Suggests) so it works here as expected because the "extra" packages are brought in via backward/reverse dependencies. The hunspell-el package for example has reverse weak dependency (this dependency is listed in hunspell-el as Supplements) on (hunspell and langpacks-el) meaning it will be installed when you have both hunspell and langpack-el installed. With language packages this allows to install only language packages for packages that are already installed -- you won't get KDE localization (kde-l10n-el also supplements langpacks-el) if you already don't have KDE.

You can print the reverse weak dependencies with --whatsupplements

# dnf repoquery --whatsupplements langpacks-core-el

# dnf repoquery --whatsupplements langpacks-el

I don't think it's possible to print both forward and backward dependencies with one command.
