@LeKodeur my PPA provides packages for Ubuntu Bionic and Xenial. The package available for kodi v18 is kodi-pvr-mythtv-dev.

Is the APT command failled ?

Also the nightly build of kodi should be uptodate.

 No, I'm on the nightly build Kodi v18 Beta2 (20180802) for Bionic but only v. 5.8.1 is available. First I removed the 'official' Kodi addon (kodi-pvrmythtv, v. 5.8.1) and apt installed your package (successfully, v. 5.8.2) but Kodi returns an error "Addon couldn't be loaded" when I start Kodi. So, removed your addon and re-installed Kodi's official kodi-pvrmythtv (v. 5.8.1) successfully. Hope this all makes sense
