Hi, those errors look like something with the user permissions could be going wrong, but we can’t tell for sure without some more information so if you could please tell us:

  1. What are you trying to achieve
  2. How are you trying to achieve it
  3. The device type you’re using
  4. balenaOS version
  5. supervisor version
  6. Additional hardware attached to the device
  7. Libraries you’re using for this

Thanks in advance!
