InstallPackageNames exits immediately
Submitted by Marek Kašík
Method InstallPackageNames exits immediately after calling:
'gdbus call --session --dest org.freedesktop.PackageKit --object-path /org/freedesktop/PackageKit --method org.freedesktop.PackageKit.Modify2.InstallPackageNames "['hplip']" "" "" ""'
(the same goes for calling it from an application using g_dbus_connection_call_sync()).
This makes it hard for applications to install a package and use that package consequently.
The same happens with InstallPrinterDrivers where the order of installation of drivers and installation of printer is essential.
This worked before in 3.14 (with Modify interface).
