I guess that is something wrong with Discover, which you actually should not use with Arch. @dalto nicely teached me this a while back

You should never use either of these to install or update software from the repos on an Arch-based distro. They are both based on packagekit which supports no manual intervention. You can very easily end up with a broken system. If you want a graphical package manager, use bauh, octopi or pamac As above, there is. It is called akm and you can install it.
