Tvheadend

Hi I am new to this forum so hope this is the right place for my question. I have been using Mamarley’s stable ppa for years without issue. I am on Ubuntu 18.04 and recently upgraded from TVHeadend 4.2.8 to 4.2.9 and now TvHeadend won’t start. I have tried everything including a full purge and re-install and also tried the unstable 4.3.0 and same thing. If anyone has got any suggestions it would be greatly appreciated! Thanks
