And, after posting the above message, in thinking "Okay, that seems to
be working okay, so I will try Update Manager again, and see what
happens", I ran Update Manager, and, after 5 minutes of Update Manager
doing nothing more than displaying "Downloading list of changes", I
tried to click on the <Close> button, which did not respond (the
button did not show as being pressed), so, in the top left corner of
the window, is some kind of an icon, upon which I clicked, which
displayed a drop down menu, which included the "Close" option, which I
selected, and thence again got the

So I selected the <Force quit> option.
