Maybe this can help you to detect the problem.
Code:

I fix the error installing libxkbcommon-x11-0.
It is a missing dependency? Code:
$ sudo apt install libxkbcommon-x11-0 |

calibre does not come bundled with X11 libraries. Those have to be present on the system along with some other basic libraries such as C and C++ runtimes, freetype, fontconfig, etc.
