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

[JeffH]

Hi,
 
I just installed NextPVR on a fresh install of Ubuntu 24.04. I didn't get any install errors and the server seems to be running fine:

Code:

jeff@NUC11PAHi7:/tmp$ service nextpvr-server status
● nextpvr-server.service - NextPVRServer
     Loaded: loaded (/usr/lib/systemd/system/nextpvr-server.service; enabled; preset: enabled)

Jun 10 11:43:50 NUC11PAHi7 systemd[1]: Started nextpvr-server.service - NextPVRServer.

The problem is I get an HTTP 500 error trying to bring up the interface with http://127.0.0.1:8866/

I've tried it using both Firefox and Brave browsers.

I've tried it using the specific IP address of the machine it's installed on, but no joy.

Any tips?

Stop the service and zip up the logs in /var/opt/nextpvr/logs and attach them.

Here ya go - thanks!

[mvallevand]

Not much to go on there. Does it work after a restart? Stick with Firefox for now too.

Martin

[JeffH]

Unfortunately restarting didn't help.

The backend started and is active after the restart, but still a 500 error in the browser.

[mvallevand]

Ok, let's see if anything gets output to stdout. Stop the server and run this and then try the browser again

Code:

sudo -u nextpvr NEXTPVR_DATADIR_USERDATA=/var/opt/nextpvr/ /opt/dotnet/dotnet /opt/nextpvr/system/NextPVRServer.dll

No joy - still a 500 error on the browser.  Looks like the command executed without errors.

Code:

jeff@NUC11PAHi7:~$ sudo -u nextpvr NEXTPVR_DATADIR_USERDATA=/var/opt/nextpvr/ /opt/dotnet/dotnet /opt/nextpvr/system/NextPVRServer.dll

Is there any message from journalctl?

[JeffH]

I typed journalctl into the terminal and it came back with a LOT of lines. I obviously don't know what I'm doing;-)

Is there a way to narrow down the output from journalctl?

[mvallevand]

Maybe look at the last 100 lines with less

sudo journalctl -n 100 | less
