Sorry for the bureaucracy, but this bug is basically a dupe of https://fedorahosted.org/rel-eng/ticket/6246 (and related to https://github.com/fedora-infra/bodhi/issues/504 ) , which I'm filing so we can track it properly through the release blocker process. KDE live image compose failed for 23 Beta TC4. This is because KDE dependencies in 23 'stable' are broken at present, which in turn is because Bodhi screwed up https://bodhi.fedoraproject.org/updates/FEDORA-2015-14271 . It seems like about half the packages from that update have turned up in https://dl.fedoraproject.org/pub/fedora/linux/development/23/ , but notably *not* kf5-filesystem , which a lot of the ones that *were* pushed depend on. Until the whole update is either backed out or properly pushed stable, KDE live composes are going to fail. This is an automatic Beta 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 " - https://fedoraproject.org/wiki/QA:SOP_blocker_bug_process#Automatic_blockers
The push was fixed and we got a KDE live for 2015-09-10: closing.
