Nrjavaserial upgrade causes "Serial Error: Port /dev/ttyACM0 does not exist"

had same issue z-wave (Razberry) ACM0 not working with latest builds. i was using openhabian to update my system. As nolan_garrett was saying something wrong with OS.

After those two steps, i am back in business.

  • Update system sudo apt-get update
  • Install: liblockdev1-dev package sudo apt-get install liblockdev1-dev

All works again.
