Hello Michael,
 
emacs -Q does indeed make the problem go away.  I eventually tr= acked it down to this line in my config:
 
(add-to-list 'tramp-remote-path 'tramp-own-remote-path)
 
When I commented that out, things started working, but of course the= n TRAMP couldn't find some remote executables (git for magit, for example= ).
 
Curiously, swapping back to emacs 26 and then uncommenting that line= kept things working.  Which is odd because emacs 26 is where
things started going wrong and I had upgraded to emacs 27 to see if = it would be fixed.
 
I had previously disabled some small packages in my config that I wa= sn't really using, but was still seeing failures until the line above was=
commented out.  So I don't think those packages have anything t= o do with this.
 
It's a mystery, but it's at least working now, for unknown reasons.&= nbsp; As I noted in th bug report, things just stopped working witho= ut any
config changes on my end, so I'm not sure what the cause was.  = Just as mysteriously, they're now working again.
 
David

That doesn't tell too much=
. If the test above doesn't help, could you
please start

=
=23 emacs -Q --eval '(setq tramp-verbose 6)'

and rerun the tes=
t=3F There will be a Tramp debug buffer; pls show it.

Best reg=
