module: pkgutil
short_description: OpenCSW package management on Solaris
description:
- This module installs, updates and removes packages from the OpenCSW project for Solaris.
- Unlike the M(community.general.svr4pkg) module, it will resolve and download dependencies.
- See U(https://www.opencsw.org/) for more information about the project.

    description:
    - The name of the package.
    - When using C(state=latest), this can be C('*'), which updates all installed packages managed by pkgutil.

    description:
    - The repository path to install the package from.

    description:
    - Whether to install (C(present)/C(installed)), or remove (C(absent)/C(removed)) packages.
    - The upgrade (C(latest)) operation will update/install the packages to the latest version available.
    type: str
    required: true
    choices: [ absent, installed, latest, present, removed ]
  update_catalog:
    description:
    - If you always want to refresh your catalog from the mirror, even when it's not stale, set this to C(yes).
    type: bool
    default: no
  force:
    description:
    - To allow the update process to downgrade packages to match what is present in the repository, set this to C(yes).
    - This is useful for rolling back to stable from testing, or similar operations.
    type: bool
    default: false
    version_added: 1.2.0
notes:
- In order to check the availability of packages, the catalog cache under C(/var/opt/csw/pkgutil) may be refreshed even in check mode.
