Where does DNF (Fedora) store downloaded packages?
DNF stores downloaded packages and metadata in /var/cache/dnf, in various per-repository subdirectories.
By default, after a successful installation, the packages are removed. You can change this behavior with keepcache in /etc/dnf/dnf.conf.
Note that PackageKit — in use on Fedora Workstation by default — puts packages in /var/cache/PackageKit, so you can get duplicates. Harmonizing this is work in progress.
It doesn't - once a package is installed the downloaded rpm file is not normally kept.
The file will be in the cache (in /var/cache/dnf) briefly but once it has been successfully installed that will be removed.
