Under Xubuntu 20.10, I checked for some updates launching update-manager with a terminal, and then switched to another software, leaving update-manager open.
When I wanted to close update-manager by clicking on OK, it hanged, so I was forced to close it by using ctrl-c on the terminal window.
This is the traceback I got as soon as update-manager closed:
~$ update-manager

^Clsb_release returned exitcode: -2
