To clear this up, the above is both true and untrue in a way :) It's gnome-software that drives the periodic downloads, but the actual downloading is done through PackageKit. The daily metadata downloading can be currently turned off with a super-secret gsettings key. It was originally only meant for the live cd use case where we needed to turn off metadata downloads in order to avoid filling up the ramdisk, but I have heard that people have found this useful for other cases as well. Periodic metadata downloads can be disabled with: gsettings set org.gnome.software download-updates false and reset to the default value (re-enabled) with: gsettings reset org.gnome.software download-updates Furthermore, there's a new NetworkManager API in the works that allows apps to determine if connections are 'metered' to avoid downloading updates. This API actually landed in NetworkManager a few weeks ago, and there's a plan to make use of it in gnome-software. Look out for improvements in this area :) Hope this clears things up, Kalev -- desktop mailing list desktop@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/desktop
