Thanks to @TheLapin for bringing this up again.
@ActionA: The following: sudo apt-get update && sudo apt-get dist-upgrade
produced lots of errors for me. Some file system errors actually. After battling through them and rebooting osmc, it automatically fixed some filesystem errors as my Pi hanged but got stuck on this error:
dpkg: unrecoverable fatal error, aborting: files list file for package 'rbp2-image-4.9.29-15-osmc' contains empty filename E: Sub-process /usr/bin/dpkg returned an error code (2)
was the error I got after several attempts. After some more fighting, the following got me past it:
sudo rm /var/lib/dpkg/info/rbp2-image-4.9.29-15-osmc.list
then I re-ran:
sudo apt-get update && sudo apt-get dist-upgrade with success.
After that my harmony remote actually responded! Mind you, it was triple commands. I tried reducing a setting in the harmony settings to ‘0’ (see this post: https://discourse.osmc.tv/t/multiple-remote-presses-in-2015-07-1/6507/4) but it didn’t change anything. Picked mce in the remotes sections under MyOSMC and it also didn’t change anything.
At the end, I chose the lircd remote for harmony and it worked. Picking the mce6 continued to produce triple commands being sent.
Either way, everything is working now. Although I forgot what “Exit” command is supposed to be mapped (I picked return) and all is good.
I probably could have resolved this by just formatting the sdcard, but I’m too stubborn at this point.
