Hello,

I am using Calibre (4.99.4+dfsg+really4.12.0-1build1 from ubuntu-focal-universe).

I was using normally, but now I got the following messages when tried to run Calibre:

(base) icamps@varadero:~$ calibre
Gtk-Message: 09:44:03.334: Failed to load module "pk-gtk-module"
Gtk-Message: 09:44:03.335: Failed to load module "pk-gtk-module"
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'

Any ideas?

Thanks in advance
