here is a refresher...
i first started with an issue generating a runtime error x3 when i tried to execute the SafeShutdown.py script from RetroFlag
this started just after having flashed an updated OS.
i chased that one around tyring to find a working gpio library solution not realizing that serial and one wire were both enabled in raspi-config and that was skewing my results
however i had removed RPi.GPIO and installed LGPIO per your Instruction (Hippy)
then I entered in your set by step at apython3 >>> prompt without any errors only to have errors generate upon a reboot. I captured those with redirects and posted the results.
after that i opened up my wayfire desktop to use geany.
i noticed some missing "wine 64" icons and started to investigate that!
the first thing i did there was attempt a re-install using pi-apps
that attempt failed with a system error reported by pi-apps. apparently there were some "required" dependencies that were missing!!
it warned that this was odd and there could be other corrupted or missing files.
so i opted to just re-flash and start over.
(i think i had downloaded something i shouldn't have or possibly was left over from one of the many hard-reboots i was forced to preform.
either way... i have re-flashed, properly configured with raspi-config. connected through wifi,
updated, upgraded, reinstalled the retroflag SafeShutdown.py script put redirects in place to catch the stderr out. to /tmp/SafeShutdown.log.
i have booted with my rc.local modifications you gave me temporarily reversed. to capture the errors...
for quick reference here is the SafeShutdown.py script that generated this...
the problems seams to be a "key error" and a "bad event request"
the fact that there are 3 identical errors each is telling be this is after the multiple processes have started.
but i have no idea what the real problem is.
