Of particular interest might be this line:
 touch[783]: /usr/bin/touch: cannot touch '/var/lock/subsys/ldirectord': No such file or directory

This runs in LXD, maybe a pathing or apparmor issue?

I tried the same on a real armhf device and it works right away.
(Thanks waveform to provide armhf raspi)
