I toggled TRAMP debugging with ~(setq tramp-verbose 10)~. And tested with =emacs -Q= confirmed this problem.

- Emacs version: GNU Emacs 29.0.50 (build 2, aarch64-apple-darwin21.3.0, NS appkit-2113.30 Version 12.2.1 (Build 21D62)) of 2022-03-09
- System: M1 Mac Mini, macOS Monterey Version 12.3

Here is the TRAMP debug log output:

It isn't the Tramp debug log, it is the backtrace. For analysis, I'd need
the full Tramp debug buffer *debug tramp/ssh stardiviner@localhost*.

If you believe it is too long for this ML, you could send it directly to me.

Best regards, Michael.

Indeed, the tramp debug log is too large (45M), email (sendmail) can't send it. So I paste it on
GitHub Gist here:  https://gist.github.com/stardiviner/d53fde541154cddf44db8d95c2ee15a1

Thanks. According to the traces, Tramp has sent

--8<---------------cut here---------------start------------->8---
09:46:13.813642 tramp-send-command (6) # exec ssh -l stardiviner -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none localhost
--8<---------------cut here---------------end--------------->8---

Then the password request was answered successfully

--8<---------------cut here---------------start------------->8---
09:46:14.069608 tramp-accept-process-output (10) # *tramp/ssh stardiviner@localhost* 0 run nil

(stardiviner@localhost) Password:
09:46:14.070100 tramp-action-password (3) # Sending Password
--8<---------------cut here---------------end--------------->8---

However, Tramp didn't see any shell prompt afterwards. Instead (when you
have quit the connection), it sees

--8<---------------cut here---------------start------------->8---
09:46:53.454713 tramp-accept-process-output (1) # Quit: "Quit", ""

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Do you see the same when calling the ssh command above from a shell? Do
you see a shell prompt there?

Best regards, Michael.

I tested command "ssh stardiviner@localhost" to ssh login my localhost account. It works fine and
the shell prompt show up. But I'm using Zsh on macOS by default, and the Zsh prompt is not standard,
it's customized by oh-my-zsh project. Maybe this is related? Then I tested with disable oh-my-zsh's
.zshrc profile file. And try Emacs tramp "/ssh:stardiviner@localhost:~". Still has suspend problem.

PS. My zsh version: zsh 5.8.1 (arm-apple-darwin21.3.0)

Tramp and zsh didn't fall in love ever. You need to disable the zle
(built-in zsh), consult the Tramp manual about.

Hm ... like this?

[[ $TERM == "dumb" ]] && unsetopt zle && PS1='$ ' && return

We got it to work from Linux (Debian) to both OpenBSD and
SunOS, remember? (Actually if I didn't have these files
I don't know how much I would remember. But I use it every
day, to the OpenBSD account filesystem, so thumbs up
regardless ...)

But, now technically speaking ... it doesn't look like zsh

Thank you, Michael.

Indeed, It tested on Raspberry Pi Bash, it works fine now. Seems problem indeed is on Zsh.

I found TRAMP Info manual mentioned setting remote server shell for TRAMP. I tried bellowing elisp setting:

#+begin_src emacs-lisp

             (list (regexp-quote "/ssh:Mac-mini.local:")
                   "remote-shell" "/bin/bash"))
(add-to-list 'tramp-connection-properties
             (list (regexp-quote "/ssh:stardiviner@localhost:")
                   "remote-shell" "/bin/bash"))

The 1~3 part of sexps should let TRAMP invoke Bash on my macOS instead of default login Zsh. But
it's not working. Maybe I understand that wrong? Or my setting is wrong?

Your setting looks OK. Do you have tried this with "emacs -Q"? And you
know, that you must perform these settings *before* accessing the
respective host the first time.

If it doesn't work, pls produce Tramp traces with tramp-verbose set to 10.

Best regards, Michael.

Thanks for helping me to troubleshooting this problem. Sorry for late response.

Today I spend some time on this task. Running command "emacs -Q" and load the following config:

#+begin_src emacs-lisp
(when (eq system-type 'darwin)
  ;; Each SYMBOL is control, meta, alt, super, hyper or none.
  ;; Use Alt key as Hyper
  (setq mac-option-modifier 'super) ; S- ~
  ;; Use Command key as Meta
  (setq mac-command-modifier 'meta)
  ;; (setq mac-right-option-modifier 'hyper)
  (global-set-key [kp-delete] 'delete-char) ; sets fn-delete to be right-delete
  )

(require 'tramp)

(setq tramp-verbose 10)

(add-to-list 'tramp-connection-properties
             (list (regexp-quote "/ssh:raspberry_pi-wireless:")
                   "remote-shell" "/bin/bash"))
#+end_src

The Raspberry Pi Linux default login shell is Zsh, with upper settings, I can normally access with
TRAMP. After testing, it works. So I guess the problem is still on my Emacs config.

Really sorry about this wasted your time.
