The problem is a #if QT version check in src/calibre/headless/main.cpp somehow failing to properly detect the right qt version. Upstream has done this commit: https://github.com/kovidgoyal/calibre/commit/eb43e53372bbd4a4d7d51eb6c0beec5f39312e4f Which fixes this by getting rid of the #if, so we should probably cherry-pick this. It would be good to actually know why the #if fails though ... This may be related to the building of the headless plugin not honoring rpm_opt_flags. I'll cherry pick this soon if they don't do a new release with it. (They usually do releases weekly around thursday/friday). calibre-2.69.0-1.fc25 has been pushed to the Fedora 25 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-9eb14544b5 calibre-2.69.0-1.fc25 has been pushed to the Fedora 25 stable repository.

Hi, Headless mode (and book import from the gui which seems to depend on headless mode for some books) fails when using qt 5.7 (with the Fedora calibre-2.68.0 pkgs on Fedora 25), the error reported is: " This application failed to start because it could not find or load the Qt platform plugin "headless" in "/usr/lib64/calibre/calibre/plugins". Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb. Reinstalling the application may fix this problem. " I've managed to hack around this (fixing using calibre under X at least) with this: --- /usr/lib64/calibre/calibre/gui2/__init__.py~ 2016-09-17 17:58:30.000000000 +0200 +++ /usr/lib64/calibre/calibre/gui2/__init__.py 2016-09-25 15:02:29.831338885 +0200 @@ -876,10 +876,7 @@ self.file_event_hook = None if override_program_name: args = [override_program_name] + args[1:] - if headless: - if not args: - args = sys.argv[:1] - args.extend(['-platformpluginpath', sys.extensions_location, '-platform', 'headless']) + headless = False self.headless = headless qargs = [i.encode('utf-8') if isinstance(i, unicode) else i for i in args] self.pi = plugins['progress_indicator'][0] @@ -1186,6 +1183,7 @@ _ea_lock = Lock() def ensure_app(headless=True): + headless = False global _store_app with _ea_lock: if _store_app is None and QApplication.instance() is None: Which allows me to import books again. I realize this is a useless fix, but it proves that the problem is with headless and that calibre works fine otherwise. I've filed an upstream bug for this here: https://bugs.launchpad.net/calibre/+bug/1627494 Hopefully upstream will fix this soon, if not we should probably use my hack to at least get the gui to work properly on F25.
