NextPVR on Ubuntu 24.04 Server Running, Web interface not so much

[JeffH]

OK, I started the server and ran the command.  I didn't see anything like an Error except for a gnome-shell error prior to starting NextPVR.

Code:

I guess you need -n 1000 or more we don't see the crash there.

I did a fresh restart, verified the status of nextpvr-server = Active and ran the journalctl command.  The output is below (I couldn't spot anything suspicious, maybe you can?)

I also did another test - I installed NextPVR on an old laptop running the same version of Ubuntu 24.04 - It worked perfectly.  So, it does work and I do know how to install it!  

I also tried shutting down a couple other apps that have local web servers (Syncthing & Duplicati) but that didn't help.

Seems there's something about the machine I'm trying to install it on that's blocking the web server.

[mvallevand]

Correct there is no issue with 24.04 whatever is happening is your local configuration.

You are using journalctl incorrectly. I just showed you a way to limit the logs, so you can browse it. You should be able to see the service start if you don't limit it to 100 lines but I can't guarantee that this will show why the 500 is occurring.

Since I just rebuilt the system a couple weeks ago, I'm thinking I'll just start over from a clean install. I'll install NextPVR first, then start installing apps one at a time until NextPVR breaks (or I can't get something to work) and hopefully that will expose the culprit.

BTW Martin, I really appreciate all your help troubleshooting! You've been super responsive and patient.

[mvallevand]

Good luck, there did seem to be extra errors not related to NextPVR in the journal so a reinstall makes sense.
