After upgrading to 19 and finding a key addon broken i reverted to 18,

tried purging kodi* and re installing but now get this error when installing kodi-pvr-hts 



The following packages have unmet dependencies:
 kodi-pvr-hts : Depends: kodi-api-pvr (= 5.10.3)
E: Unable to correct problems, you have held broken packages.

Seams to be similar issues with kodi-pvr-iptvsimple

From what i can tell, it looks like Kodi 18.9 no longer provides kodi-api-pvr the last one that did was 18.8 which is not availabe in the team-xbmc-old repository so breaks not only hts but ipsimple as well.

use the kodi-old PPA instead of the stable PPA

I did use kodi-old as not the first time ive had to revert.

In the end i just fixed the plugin to work under 19, as could not get hts to install after reverting to the kodi-old repository (installs 18.9) due to no packate providing kodi-api-pvr, so runing 19 matrix and all is well again.
Other than the Minix Neo U1 that is not supported with kernel 4.19 (amlogic S905 CPU) so no Matrix and Openelec for it...
