    When using "Device Test" on Qt Creator to connect to linux device, the following error happens:

    Connecting to host...
    Checking kernel version...
    Linux 4.14.98+g5d6cbeafb80c aarch64

    Checking if specified ports are available...
    All specified ports are available.

    Checking whether an SFTP connection can be set up...
    Error setting up SFTP connection: File transfer failed: sh: /usr/libexec/sftp-server: No such file or directory
    Connection closed

    Checking whether rsync works...
    rsync failed with exit code 12: sh: rsync: command not found
    rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
    rsync error: error in rsync protocol data stream (code 12) at io.c(235) [Receiver=3.1.2]

    Deployment to this device will not work out of the box.

    But actually, there is sftp(but I don't know how it searhes /usr/libexec) on my pc, and the ssh setting on QtCreator as following:

    Path to ssh executable: /usr/bin/ssh
    Path to sftp executable: /usr/bin/sftp
    Path to ssh-askpass executable: /home/samuel/Qt5.14.2/Tools/QtCreator/libexec/qtcreator/qtc-askpass
    Path to ssh-keygen executable:/usr/bin/ssh-keygen

    Anybody know why? please help me with this situation

      Hi,

      Might be a silly question but do you have sftp-server ?

        Thanks for your reply, I'm not familiar with sftp, what step should I do to make sure I have a sftp-server on my PC?
        the config under /etc/ssh/sshd_config hasn't been changed, "Subsystem sftp /usr/lib/openssh/sftp-server".

          have you already tried to sftp to your device from a Terminal?

          Regards

            @aha_1980 Sorry for my late reply, I have tried "sftp root@xxxx.xxxx.xxxx.xxxx" on my pc, and it always turns out :
            sh:/usr/libexec/sftp-server:No such file or directory.

            No matter what value I changed to /etc/ssh/sshd_config "Subsystem sftp /usr/lib/openssh/sftp-server" or "Subsystem sftp internal-sftp.

            Do you have any idea? please help me with this situation

              Honestly I have no idea, but it seems the problem is unrelated to Qt, it already happens on system level.

              https://unix.stackexchange.com/questions/93584/sftp-server-fails-to-start might give you some inspirations...
