Hello,
I compiled Tvheadend 4.2.6-7 (which is the newest fom stable branch) from Git and installed the deb packages on an ubuntu 18.04 Server and everything worked without problems.
Then the first Setup via the Webinterface channel scanning went wrong. It took a few seconds and scan status was 100% with only 1 found muxes and no services.
I even tried Tvheadend 4.3 developer version but same issue.
So I purged the Tvheadend 4.2.6-7 and installed an older version 4.2.5-29 (from which I compiled earlier this year) and everything worked fine, channel scanning and so on...
Now I can say that version 4.2.5-29 is the last working version of Tvheadend with my Cine S2 V6. Here the message from grep:
