DNF: how to I check which package installed a specific package?

Question

example: I can see a package "XYZ" has been installed. I want to find out which package installed XYZ because it's one of its dependencies.

Thanks

A single package can be required by multiple different packages so it's not always obvious, specially if you installed a bulk of them.

Ways to check it:

1. sudo dnf repoquery --whatrequires package or rpm -q --whatrequires package

2. Simply running sudo dnf history package| egrep -w 'install|upgrade' will show you all the operations with the package and by inspecting them you can infer which other packages required the package.

3. Also, you can simply try uninstalling the xyz and see what it leads to: sudo dnf --assumeno remove package or rpm -e --test package
