I had Plex Home Theater installed and mostly working on Ubuntu 14.04 earlier. While attempting to resolve another problem (some videos had no audio and played too quickly), I uninstalled Plex Home Theater via:
sudo apt-get --purge remove plexhometheater
rm -rf ~/.plexht
sudo apt-get --purge autoremove
And then proceeded to reinstall it with
sudo apt-get install plexhometheater
Unfortunately, once I tried running the executable at /opt/plexhometheater/bin/plexhometheater, it would end prematurely with the message "Unable to find path to XBMC data files!".
Another thread states that this problem can be fixed by exporting /usr/share/xbmc to $XBMC_HOME. Unfortunately, that doesn't fix my problem because Plex exits prematurely with another error message.
On the other hand, running the executable with --version results in the following:
$ /opt/plexhometheater/bin/plexhometheater --version
XBMC Media Center 1.3.5.dev-git

It looks like I installed XBMC as Plex? Is that possible? Does anyone have a fix for this?
