Troubleshooting

Molecule 25.2+ introduced breaking changes.

Failed to set permissions ... when becoming an unprivileged user

ACL management utilities are required for become: user. These may be left out for minimal install images.

[ERROR]: Task failed: Failed to set permissions on the temporary files Ansible needs to create when becoming an unprivileged user (rc: 1, err: chmod: invalid mode: ‘A+user:{USER}:rx:allow’

# Always install ACL packages as part of role dependencies.
apt install acl

YAML files reverted on test execution

File linking or caching issue with IDE or Molecule.

Suspected causes

• SSHFS connection drops.
• Rebooting while molecule testing instances are running.
• IDE environment using stale file handle.

Clear all caches and re-open affected file:

1. CLOSE the file with the issue in the editor and reopen/save. Re-run tests.
2. Remove all molecule test state from all tested roles. Re-run tests.

   for x in $(ls -1); do pushd ${x} && molecule destroy --all && popd; done

3. Clean out all ansible caches. Re-run tests.

   molecule destroy --all
   molecule reset
   rm -rfv ~/.cache/molecule/*
   rm -rfv /tmp/ansible-tmp*
   rm -rfv /tmp/ansible-cache/*
   rm -rfv ~/.ansible/*
   rm -rfv ~/.ansible_async/*
