Tvheadend

I've installed tvheadend on libreelec 9.2.3 and set it up with no problem. However, I wanted to install it on an x86_64 PC with Ubuntu 20.04 and found I had to use snap to install. I got none of the usual setup questions and when the install was done I just went to 127.0.0.1:9981 and configured as usual. I was able to watch TV from my HDHomerun tuners but I wanted to setup a recording directory on a location on a second hard drive and I keep getting permission issues.

I've tried making the permissions 777, but no luck. I googled for help and I see comments about changing owner of the directory to hts and give the right permissions.

However, I have no hts user in ubuntu. I have user hts for the webpage setup and Kodi, but not at the system level.

What am I missing??

UPDATE: originally the recording path was set at installation to /root/snap/tvheadend/139. If I leave it set to that the recordings are stored there correctly with an owner of 'root'. Since /root is on my boot drive I wanted the recordings on my 1TB HD which is mounted at /home/. Just changing the owner of the recording directory to root and setting the permissions didn't work.
