Bug Description

This is a relatively recent error, and calibre was working fine a few days ago.
Now it fails to start up, and on running it from the command line, I am getting this error:

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'

Calibre Version: 4.99.4
OS: Ubuntu 20.04.1
Python version: 3.8.5

I do not provide support for people using distro provided packages. If you are using a distro provided package, uninstall it and install the official calibre binary from https://calibre-ebook.com/download_linux and if you can reproduce the bug with that, re-open the ticket. Of course, if you are already using the official binary, apologies and feel free to re-open the ticket immediately :)

 status invalid

Changed in calibre:
status: New → Invalid

Yes, I seemed to be using the distro provided binary. Shifting to the official package solved the issue. My apologies and thank you!

I have a kind request, if the bug does not affect the upstream project, instead of marking it as invalid, please change the affected package to the Ubuntu one, or duplicate the bug report to another that affects the Ubuntu package, otherwise the Ubuntu maintainers will not know about the bug, and duplicating identical bug reports increases their heat hence importance.
