I installed the openatv 6.1, of course it does not have the drivers impregnated so the tuners do not work, but I have checked the epg versions installed and they are working. this and what I found:
File versions of the openpli (not working): libc6 - 2.19-r0
File versions of openatv (working): libc6 - 2.25-r0 - GLIBC (GNU C Library) python-compression - 2.7.13-r1.3 - Python high-level compression support python-lzma - 0.0.8-r0 - Backport of Python 3.3's 'lzma' module for XZ/LZMA compressed files enigma2-plugin-extensions-epgimport - 1.0+git170+9bb6152-r36 - Imports xmltv files into the EPG cache of enigma2 Imports xmltv files into the EPG cache of enigma2. enigma2-plugin-systemplugins-abmcustommiximporter - 6.1+git2135+b4ab08b-r3 - systemplugins-abmcustommiximporter Imports ABM CustomMix files from Github. enigma2-plugin-systemplugins-channelsimporter - 6.1+git2135+b4ab08b-r3 - systemplugins-channelsimporter Imports a copy of the channel list from a remote receiver and loads it on the local receiver. enigma2-plugin-systemplugins-dsayerscustommiximporter - 6.1+git2135+b4ab08b-r3 - systemplugins-dsayerscustommiximporter systemplugins-dsayerscustommiximporter epgimport-rytec - 20171116-r0 - Rytec's sources and channels for the EPG importer Rytec's sources and channels for the EPG importer. python-importlib - 2.7.13-r1.3 - Python import implementation library The Python Programming Language. python3-importlib - 3.5.2-r1.0 - Python import implementation library The Python Programming Language. enigma2-plugin-systemplugins-crossepg - 0.8.5+gitr468+6250bd3-r0 - systemplugins-crossepg
At this point you have to be able to install the same versions in the openpli to have everything working again, I think ....
