As of Ansible 2.7+, this module also supports C(YUM4), which is the "new yum" and it has an C(dnf) backend. - By default, this module will select the backend based on the C(ansible_pkg_mgr) fact. default: "auto" choices: [ auto, yum, yum4, dnf ] type: str version_added: "2.7" name: description: - A package name or package specifier with version, like C(name-1.0). - Comparison operators for package version are valid here C(>), C(<), C(>=), C(<=). Example - C(name>=1.0) - If a previous version is specified, the task also needs to turn C(allow_downgrade) on. See the C(allow_downgrade) documentation for caveats with downgrading packages. - When using state=latest, this can be C('*') which means run C(yum -y update). - You can also pass a url or a local path to a rpm file (using state=present).

Note that setting allow_downgrade=True can make this module behave in a non-idempotent way.

This caused problems when packages specified by filename or url had to be installed or removed together. In 1.9.2 this was fixed so that packages are installed in one yum transaction. However, if one of the packages adds a new yum repository that the other packages come from (such as epel-release) then that package needs to be installed in a separate task. This mimics yum's command line behaviour. - 'Yum itself has two types of groups. "Package groups" are specified in the rpm itself while "environment groups" are specified in a separate file (usually by the distribution). Unfortunately, this division becomes apparent to ansible users because ansible needs to operate on the group of packages in a single transaction and yum requires groups to be specified in different ways when used in that way. Package groups are specified as "@development-tools" and environment groups are "@^gnome-desktop-environment". Use the "yum group list hidden ids" command to see which category of group the group you want to install falls into.' - 'The yum module does not support clearing yum cache in an idempotent way, so it was decided not to implement it, the only method is to use command and call the yum command directly, namely "command: yum clean all" https://github.com/ansible/ansible/pull/31450#issuecomment-352889579' #
