“The Fedora 12 release contained changes in the default
PackageKit behavior that allow installation of packages by users in
cases where:“* the user is logged in on the local console, and
* is installing packages signed with a previously trusted key,
and
* is using a previously configured and trusted repository“After more discussion and thought, though, the package
maintainers have posted to the fedora-devel-list mailing list
agreeing to provide an update to Fedora 12’s PackageKit.”
