The other issue is that dnf and PackageKit each download their own copies of this metadata. Delete /var/cache/dnf and /var/cache/PackageKit, reboot and within a couple hours du will show: 108M dnf 132M PackageKit -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org
