Bug#888315:

[Markus <markus@the-grue.de>]

Hello,
 
I fixed my problem. strace indicated a problem with netdata's sqlite database. That was not reported in any netdata output. So I deleted the contents of /var/cache/netdata and all was fine.
 
So while my problem is solved, there might be two problems that caused this bug report:
- sqlite conversion seems to be faulty. At least that's what the strace output suggests. I attached it for completeness and maybe an upstream bug report.
- `apt purge netdata` should delete or offer to delete /var/cache/netdata. If it would have done that, my problem would have been fixed quite soon:
 
[gru:~] % apt purge netdata

* "could not find cloud.conf"
Yes, I also saw that message when I ran the natively installed netdata daemon
 
* output from starting netdata in the foreground

That's it. Exit code 1, not helpful...
 
So you could fix that bug, but it would be good if the above mentioned problems would be addressed.
 
Thanks for your work as a maintainer!
