Current Behavior

Build on Fedora 42 - sftp transfer mechanism failed

This warning/error appears specifically on F42, on F41 and earlier versions not.

...
[WARNING]: sftp transfer mechanism failed on [127.0.0.1]. Use ANSIBLE_DEBUG=1
...
bash: line 1: /usr/lib/sftp-server: No such file or directory
...

To fix it, it is necessary to add additional Ansible var ANSIBLE_SSH_TRANSFER_METHOD to use scp protocol, like this:

...
    ansible_env_vars = [
      "ANSIBLE_PIPELINING=True",
      "ANSIBLE_REMOTE_TEMP=/tmp",
      "ANSIBLE_SSH_TRANSFER_METHOD=scp",
      "ANSIBLE_SCP_EXTRA_ARGS=-O",
    ]
...

I recently run

$ packer build -only=qemu.almalinux-9-gencloud-x86_64 .

and

$ packer build -only=qemu.almalinux_10_gencloud_x86_64 .

on a Fedora 43 with packer-1.15.0-1.x86_64 and both passed.

Has this been fixed via #176 which removed the need for the explicit -O flag?
