Live image creation is currently failing for Rawhide and Fedora 24 due to the glibc langpack split. anaconda fails to start as the en langpack is missing, thus the image creation fails. This is more or less the same problem as https://bugzilla.redhat.com/show_bug.cgi?id=1312607 , but I'm filing it separately since the planned 'fix' for that bug - adding the langpacks to the installer environment for the dedicated installer images - may not fix this case. Having anaconda Requires: all langpacks would probably solve this case and all other anaconda-related cases, but may be too big of a hammer, that's still under discussion. This is an automatic blocker: "Bugs which entirely prevent the composition of one or more of the release-blocking images required to be built for a currently-pending (pre-)release" (it prevents building Workstation and KDE lives for F24, both of which are release-blocking).
We've been getting lives for the last few days, so I think the glibc package changes resolved this.
