| Michael, Thanks for the hint! It still does not work.
I hope the error message is not "found remote shell prompt” when it cannot find the shell prompt :) So I added the following line in the “~/.profile” of the Linux box: [[ $TERM == "dumb" ]] && PS1='$ ' && return This changed the shell prompt to “$ “. Then I ran the following command: (setq tramp-shell-prompt-pattern "^[^>$][>$] *") Now my tramp session hang on a slightly different error message: Found remote shell prompt on ‘homes.local’ And the full trace file is below: ==== File: *debug tramp/ssh local@homes.local* ==== ;; Emacs: 26.3 Tramp: 2.3.5.26.3 -*- mode: outline; -*- ;; Location: /Applications/Emacs.app/Contents/Resources/lisp/net/tramp.elc Git: nil 19:09:20.274873 tramp-get-connection-property (7) # ~ undef 19:09:20.274982 tramp-get-connection-property (7) # process-name nil 19:09:20.275043 tramp-get-connection-property (7) # process-name nil 19:09:20.275099 tramp-get-connection-property (7) # process-buffer nil 19:09:20.275159 tramp-get-connection-property (7) # process-buffer nil 19:09:20.275208 tramp-set-connection-property (7) # process-buffer nil 19:09:20.275423 tramp-maybe-open-connection (3) # Opening connection for local@homes.local using ssh... 19:09:20.275648 tramp-get-connection-property (7) # login-args undef 19:09:20.275718 tramp-get-connection-property (7) # login-args undef 19:09:20.275799 tramp-get-connection-property (7) # process-name nil 19:09:20.275859 tramp-get-connection-property (7) # process-buffer nil 19:09:20.297101 tramp-set-connection-property (7) # vector (tramp-file-name ssh local nil homes.local nil nil) 19:09:20.297305 tramp-maybe-open-connection (6) # /bin/sh -i 19:09:20.297382 tramp-get-connection-property (7) # vector (tramp-file-name ssh local nil homes.local nil nil) 19:09:20.297455 tramp-get-connection-property (7) # check-remote-echo nil 19:09:20.297516 tramp-get-connection-property (7) # check-remote-echo nil 19:09:20.305218 tramp-accept-process-output (10) # *tramp/ssh local@homes.local* run t #$ 19:09:20.305314 tramp-get-connection-property (7) # check-remote-echo nil 19:09:20.305390 tramp-get-connection-property (7) # check-remote-echo nil 19:09:20.305447 tramp-wait-for-regexp (6) # #$ 19:09:20.305525 tramp-get-connection-property (7) # login-program undef 19:09:20.305588 tramp-get-connection-property (7) # login-args undef 19:09:20.305649 tramp-get-connection-property (7) # login-env undef 19:09:20.305718 tramp-get-connection-property (7) # async-args undef 19:09:20.305774 tramp-get-connection-property (7) # connection-timeout undef 19:09:20.305832 tramp-get-connection-property (7) # temp-file undef 19:09:20.306042 tramp-set-connection-property (7) # temp-file /var/folders/zw/855cv2ts5zggnjs0f4p__7xr0000gp/T/tramp.abfFDT 19:09:20.311624 tramp-maybe-open-connection (3) # Sending command ‘exec ssh -l local -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none homes.local’ 19:09:20.311709 tramp-get-connection-property (7) # process-name nil 19:09:20.311795 tramp-get-connection-property (7) # remote-echo nil 19:09:20.311865 tramp-send-command (6) # exec ssh -l local -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none homes.local 19:09:20.311922 tramp-get-connection-property (7) # process-name nil 19:09:20.311982 tramp-get-connection-property (7) # chunksize nil 19:09:20.312036 tramp-set-connection-property (7) # last-cmd-time (24205 12880 312018 0) 19:09:20.312104 tramp-send-string (10) # exec ssh -l local -o ControlMaster=auto -o ControlPath='tramp.%C' -o ControlPersist=no -e none homes.local 19:09:20.312284 tramp-get-connection-property (7) # process-buffer nil 19:09:20.312400 tramp-set-connection-property (7) # first-password-request 19:09:20.312591 tramp-process-actions (3) # Waiting for prompts from remote shell... 19:09:21.191932 tramp-accept-process-output (10) # *tramp/ssh local@homes.local* run t Welcome to Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-76-generic x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage * Kubernetes 1.18 GA is now available!
