Kodi Server Plugin - EPG Update Failure

[ceejayemm]

I am testing out Kodi 21 / LibreElec 12 (Beta 2) on an Intel Linux server using the latest NPVR Kodi server plugin.

The EPG update process fails with (repeated several times):

2024-04-28 02:44:54.729 [DEBUG][32] SD using existing token

and a slightly different error a bit later:

This happens with a manual or a scheduled update.

Could you run dotnet --info to check where 6.0.29 is installed and append /6.0.29 and look for those missing files. I checked the tar file LE downloads and they were there.

I decided to test on my VM test install x64 for the server and SD worked fine and the folder was ls /storage/.kodi/addons/tools.dotnet-runtime/bin/shared/Microsoft.NETCore.App/6.0.29/

For others that read this note it is a LibreELEC package not Kodi addon.

It turns out that although I had updated all the addons in my system, which included the NextPVR Client addon, I had forgotten that the Server installation does not update automatically through this process.  I downloaded the latest NextPVR Server zip file through its addon and let it update.  After this completed I was able to to successfully update the EPG.

Thanks for your help.

Glad it works but there is something odd there for sure,

- the server does automatically update, once the updated PR is approved and distributed.
- you were already running 6.1.5.231022 so it wouldn't need to update.
- I tested with the basic zip file, I didn't need to manually pull anything.
- those missing files were part of the dotnet install that is managed by LE not the addon.

It probably was a corrupt dotnet install but maybe with something for the NextTool work too?

My LE system was originally build as an 11.x installation and then upgraded via the various release candidate and beta releases to reach v12 Beta 2 so it might have been part of that process.  Once the release v12 is available I will rebuild this server to get the full release version.

Thanks

No the service addon is python so it will install on 11 or 12 and, RPi, various ARM and X64. Dotnet might need aarch version though but that would have been ARM.
