I have same problem, too. My Angstrom 2018.06 hasn’t these packages, so I installed them after with these commands.
After update/upgrade, I have problem to make manual reboot. Linux give these messages and don’t perform reboot!!!
So, it is impossible to save , for example, a static IP set with connmanctl commands.
Have you similar issue after update/upgrade your Angstrom 2018 system???
