I am attempting to create a snap for a PyQt5 project. See http://github.com/ihaywood3/DEXBot/tree/snap Got keys from plugin meta data ("xcb") QFactoryLoader::QFactoryLoader() checking directory path "/snap/dexbot/x9/usr/bin/platforms" ... Cannot load library /snap/dexbot/x9/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so: (/snap/dexbot/x9/usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5: undefined symbol: _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE) QLibraryPrivate::loadPlugin failed on "/snap/dexbot/x9/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so" : "Cannot load library /snap/dexbot/x9/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so: (/snap/dexbot/x9/usr/lib/x86_64-linux-gnu/libQt5XcbQpa.so.5: undefined symbol: _ZNK14QPlatformTheme14fileIconPixmapERK9QFileInfoRK6QSizeF6QFlagsINS_10IconOptionEE)" This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb, vnc. Reinstalling the application may fix this problem. Aborted (core dumped) I cannot get past this error. I have included desktop-qt5 as a part, and I cannot understand why all required Qt5 libraries are not available. The missing identifier ("PlatformTheme14...") is found in the platform theme plugins libqgtk2.so and libappmenu-qt5.so, both are available in the snap.
