synchronize not working with executable=/bin/bash

[PhracturedBlue]

Migrated from: https://github.com/ansible/ansible/issues/71220

SUMMARY

In our environment, for most systems, /bin/sh is linked to /bin/bash, but on some hosts it is /bin/dash. We use 'set -eo pipefail' in our shell rules, so we need to always use /bin/bash. To simplify having to set this in every task, we set executable=/bin/bash in ansible.cfg Doing so causes an error using the synchronize module:

synchronize works fine without this setting. On the controller, /bin/sh is symlinked to /bin/dash On the inventory_host, /bin/sh is symlinked to /bin/bash /bin/bash is available on both hosts

What distro and release is the controller as well as the remote hosts in the inventory?

[shipilovds]

I have the same issue. Ansible: 2.9.13 Controller: Fedora 31 Host: Ubuntu 20.04

Is there any news?

[rbkaspr]

I'm hitting this issue too, tested with ansible host being Ubuntu 20.04 and centos 7, with remote host being RHEL 7

Has there been any movement on this?

[braindevices]

same problem here ubuntu 20.04 and centos 8 remote: Python 3.6.8 local: Python 3.8.5, ansible 2.10.3 in ~/.ansible.cfg I have:

executable = /bin/bash

It only happens when try to sync controller to remote:

ansible.posix.synchronize:
        src: /tmp/test-src
        dest: /tmp/test-dest

between 2 remote dirs or 2 local dirs are fine:

ansible.posix.synchronize:
        src: /tmp/test-src
        dest: /tmp/test-dest
      delegate_to: "{{ inventory_hostname }}"

if remote the line in .ansible.cfg but use ansible_shell_executable: /bin/bash in playbook, it works again

vars:
    ansible_shell_executable: /bin/bash

[mamh2021]

Same issue， change the ansible.cfg executable = /bin/bash to executable = /bin/sh will work well.

workaround 1： I create PR https://github.com/mamh-mixed/ansible.posix/commit/429de5c0c6885110645262e4080dc611793730a8 try to solve this issue, and add vars ansible_shell_type: sh to yaml file

workaround 2： https://github.com/mamh-mixed/ansible.posix/commit/714e42bf30e43c88b3495917a4dec184149a209a remove all code that reassign the self._play_context.shell and self._play_context.executable
