Trouble updating server on Debian-based Raspbian

@ChuckPa

I’m still having no success updating to 1.19.1.2701 on my Raspberry Pi. The pre-installation validation gives me the same error, despite having successfully updated all other packages on my system.

I read through the thread here but am still at a loss, since the directory specified in PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR is valid as you pointed out earlier.

That seems to be the only thing tripping up the pre-install script. Got any more ideas?

Thanks!
