I was getting the 'abort' message cited in the thread on upgrading Calibre.

After installing libxcb-xinerama0, when launching Calibre from Terminal I receive the following:

QApplication: invalid style override 'gtk' passed, ignoring it.
Available styles: Windows, Fusion
Using proxies: {'no': 'localhost,127.0.0.0/8,::1'}

I am running Linux Mint 18.1 Cinnamon 64-bit.

Thanks!

Best,
Simon
