Somewhere there is a mismatch. When deploying fresh undercloud I get error

./builddir/install-undercloud.log:2020-12-21 11:07:02,763 p=30959 u=root n=ansible | 2020-12-21 11:07:02.762141 | 52540000-0011-172f-d7e6-000000000826 |      FATAL | ensure podman and deps are installed | remote-u | error={"changed": false, "failures": ["podman-1.6.4 All matches were filtered out by modular filtering for argument: podman-1.6.4"], "msg": "Failed to install some of the specified packages", "rc": 1, "results": []}
./builddir/install-undercloud.log:            "podman-1.6.4"
./builddir/install-undercloud.log:        "podman-1.6.4 All matches were filtered out by modular filtering for argument: podman-1.6.4"
./builddir/install-undercloud.log:                "podman-1.6.4"

so I found a file and updated with version found in repos:

[stack@remote-u ~]$ cat /usr/share/ansible/roles/tripleo_podman/vars/redhat.yml
