Re: sh -c 'whoami' gives permission error in docker container and puts me in weird prompt/subshell

I see there's an error about tty command not found?

17:14:46.759569 tramp-wait-for-regexp (6) # 
sh: tty: command not found

I think that's from tramp-open-connection-setup-interactive-shell, this
part particularly:

    ;; Set `remote-tty' process property.
    (let ((tty (tramp-send-command-and-read vec "echo \\\"`tty`\\\"" 'noerror)))
      (unless (string-empty-p tty)
        (process-put proc 'remote-tty tty)
        (tramp-set-connection-property proc "remote-tty" tty)))
        

Here is another relevant log output for connecting to alpine:
