Hi, I am not a maintainer of this package, but have some thoughts about possible reasons of your problem.
Could you show the output of few commands? $ ls -lh /usr/lib/x86_64-linux-gnu/libQt5Core.so.* $ file /usr/lib/x86_64-linux-gnu/libQt5Core.so.* Try to reinstall libqt5core5a package: $ sudo apt-get install --reinstall libqt5core5a Best wishes, Boris
