Re: tramp (2.3.3.26.1); Tramp hangs when trying to connect in emacs for OSX 26.1

[Jeffrey Gennari]

Hi Michael,

I ran this command:

emacs -Q --eval '(setq tramp-verbose 10)' --eval '(setq tramp-debug-buffer t)' 
/ssh:address@hidden

And the bug buffer changed a bit. It is below. I’m trying the latest tramp now.

Thanks,
Jeff
