[Automotive] Getting started with automotive and qt

Fri Aug 5 23:05:15 CEST 2016

It seems as soon as I make a bit of progress I get stuck with a new error.
Now I am trying to run the neptune app using the following command:

:seek: IODevice is not open
[:0]
[CRIT | am.system] ERROR: could not not seek to position 0 in the
application database (/opt/am/apps.db): Permission denied

Interesting thing is that the file /opt/am/apps.db does not exist. The
folder "opt/am" does exist though. What should I try next?

Thanks!
Aras
