ERROR! the role 'fedora.linux_system_roles.certificate' was not found in /tmp/collections-4Lk/ansible_collections/fedora/linux_system_roles/tests/certificate/roles:/root/.ansible/roles:/usr/share/ansible/roles:/etc/ansible/roles:/tmp/collections-4Lk/ansible_collections/fedora/linux_system_roles/tests/certificate

The error appears to be in '/tmp/collections-4Lk/ansible_collections/fedora/linux_system_roles/tests/certificate/tests_many_self_signed.yml': line 16, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:
