Public bug reported: Hi
I've installed calibre (apt install calibre), and it crashes immediately when trying to start it: desktop ~ $ calibre Traceback (most recent call last): File "/usr/bin/calibre", line 20, in <module> sys.exit(calibre()) File "/usr/lib/calibre/calibre/gui_launch.py", line 73, in calibre main(args) File "/usr/lib/calibre/calibre/gui2/main.py", line 543, in main listener = create_listener() File "/usr/lib/calibre/calibre/gui2/main.py", line 514, in create_listener return Listener(address=gui_socket_address()) File "/usr/lib/calibre/calibre/utils/ipc/server.py", line 110, in __init__ self._listener._unlink.cancel() AttributeError: 'NoneType' object has no attribute 'cancel' desktop ~ $ lsb_release -a No LSB modules are available.
