Began to happen in https://ci.ros2.org/job/nightly_linux-aarch64_release/3602. This matches perfectly with this merge https://github.com/ros2/ci/pull/853 this one made the error pop up in aarch64 jobs, but this is not the cause as it is happenning on amd64

@miguelgonrod thank you for reporting this issue. This might be related to #243, which we already accounted for and fixed it in ros2/system_tests#596.

Is this only happening in aarch64? It doesn't seem to be happening in AMD anymore

[miguelgonrod]

Hi Francisco, sorry for that you, are right. In amd this seems fixed in the last builds, and yes, this is only failing on aarch64 jobs

[fgallegosalido]

This looks like a licensing issue with ARM and the Security Plugins. We will investigate this and let you know what we find
