> qt.qpa.xcb: could not connect to display :0.0 This line shows that you are not connected to X11. PDF render uses Qt library, and Qt requires some GUI environment like X11. Check X11 environment and works other X11 client programs on your machine. You must setup X11 and connect X server properly even if you don't want to use GUI. Install X11 environment and related Qt libraries, and run from GUI environment. -- YOKOTA
