Tvheadend

Hey Group.
I'm running TVheadheadend on Ubuntu16.04 Lowlatency with a TBS 6985 Quad DVS tuner card.
I did the apt upgrade - while totally crash my installation. allthough I have saving all my data to /data which is a seperate drive mounted - so actuall all settings work.
The only thing that doesn't wotrk is my EPG.

Since my install is on git source - I use this command to start tvheadend from /etc/rc.local:

/root/tvheadend/build.linux/tvheadend -c /data -l /var/log/tvheadend/tvheadend.log &

Since I running this as root - I've logged in as root and did the

 /usr/bin/tv_grab_se_tvzon --configure

But I'm getting this in my logfile when I running the rerun Intenal EPGgrabbers afterwards:

2019-07-14 14:21:45.201 [   INFO]:xmltv: /usr/bin/tv_grab_se_tvzon: grab /usr/bin/tv_grab_se_tvzon
2019-07-14 14:21:45.205 [   INFO]:spawn: Executing "/usr/bin/tv_grab_se_tvzon"

2019-07-14 14:21:45.508 [WARNING]:xmltv: /usr/bin/tv_grab_se_tvzon: grab returned no data

I do not remember this as a tricky part but I do not get why this doesn't work ? since running the grabber manually works fine and collects data - but it doesn't work in the TV headend server
