Cannot stream live TV after new install

[rosede]

I just installed NPVR v5 on an Ubuntu 20.x machine.  I use a HDHomeRun Prime as my tuner and an RPi.

I think that I have everything installed correctly.  I installed the HDHomeRun application and I can see the device and tuners and all of the channels via the HDHomeRun GUI.  NPVR scanned in the channels just fine.  I can see the channels just fine within the application, I can load the channels just in in RPi, but I just can't play anything.

From what I can tell, everything is installed correctly and functioning correctly.  I just can't stream any live TV.  Please see attached log files.

Thanks

Daryl

It looks like your live tv buffer directory set to a location that cannot be written to.

It looks like your live tv buffer directory set to a location that cannot be written to.

I've looked at permission multiple times.   My user can write to that directory.  Is there a specific user that NPVR should be installed and run as?  

Thanks

Based on everything I see in the logs the install was quite bad.  Did you do everything with the deb installer?

The install was quite bad? Yes, I used the deb installer.  I'll rip it out, and try again.

Thanks

Did you run as sudo?

In that post I ran as root, but then decided to re-run using sudo.  I still received a number of errors, so I decided to rip out Ubuntu completely, re-install the OS and re-install NPVR.  I noticed during this that the NPVR is trying to use a user called "nextpvr". I did try adding the user manually, but it failed.  So this time I installed the OS with that user.

I'll update.

Thanks

Yes the installer creates a user called nextpvr. Are you saying that is failing?

Yes, creating that user has been failing.  I didn't realize that until I tried a re-install.   I even tried creating the user manually, but it failed, so I am in the process of a complete fresh re-install.   I created the nextpvr user on installation.
