I have developed a number of what might be called ghost groups.  Some
(most) are as the result of removing groups behind gnus back.

These groups now appear in gnus -> groups buffer with an asterisk
before them as in the included image below.

The do not respond to simple C-k nor do they respond to C-u G del

Yes, the Gnus version number hasn't budged in a while. In hindsight, I
probably should have ticked it up after the obarray-to-hashtable change,
if only to help with bug-report triage.

Good, that's what I was hoping. Glad it got sorted!

Yippee !! my troubles are over.  I built emacs off May 31 sources.

The gnus version still says `Gnus v5.13' but the emacs version has
gone from 27.0.50 to 28.0.50

Starting the new gnus and attempting C-k on the ghostish groups. . just
works .. no fanfare or baloney... C-k `group' done.

Thanks for guidance and help.

And I should have asked -- also your Emacs version, as that's relevant.

This makes me think you're using an Emacs/Gnus from before my hash-table
changes (six months or so ago?), as the group strings should always be
fully decoded strings (ie there shouldn't be the escapes in the group
name). IIRC, `gnus-group-goto-group' can sometimes enter an infloop if
it can't find the group (which is a bug).

That doesn't really explain why this would infloop, though, as the group
name is not multibyte.

This appears to be a completely different problem? At least, I can't
immediately think of why it would be related to the two errors above.
Let's put this one aside until we figure out the previous issue.

Can you `toggle-debug-on-quit', do it again, and post the backtrace?

That was my first thought too. However I am a bit dim-witted and badly
fat fingered as well. . . So was hoping for some kind of complicated
key-press solution.

For me, when I press `b' I see `checking bogus newsgroups' and the
pointer goes into eternal `working' mode.   When forced with
C-g... the messages-buffer shows:

  Checking bogus newsgroups... 
  *beep*
   Quit

When I hit C-k  the pointer goes into `working' mode and never
returns.  When I force it with C-g all but one nntp group disappears
and I have to press `l' to get the full setup back

checking the Messages-buffer it only shows

   *beep*
    Quit

The vast majority of ghosts are nnimap but there are a few nnml ghosts
too.

Either backend shows the same result as above.

Does gnus-group-check-bogus-groups help?  It's bound to `b' in the
*Group* buffer.  For me, it generates an error about a nil select
method, but maybe you'll have better luck...

Can you tell us the backend of the groups, and also what happens when
you hit C-k? Is there a message of any kind?

I don't know the correct answer, but I would close down Gnus, take a
backup copy of .newsrc.eld, and then edit it by hand to remove all traces
of me^Wthe unwanted groups.

I have developed a number of what might be called ghost groups.  Some
(most) are as the result of removing groups behind gnus back. Others,
I'm not sure of their origin.

These groups now appear in gnus -> groups buffer with an asterisk
before them as in the included image below.

They do not respond to simple C-k nor do they respond to C-u G del

How can I get rid of them?
