Emby Server not starting

[kappa89 0]

Hi,

 

I have a Linux box with armhf CPU, and I installed Ubuntu 16.04 LTS.

 

The apt installation of Emby runs with no problem (Downloading also all the Mono dependencies) but I wasn't able to start the Server.

 

Here is the content of /var/log/emby-server.txt

[ERROR] FATAL UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object

Enyone knows how to fix it?

 

Thank you in advance

Hi, we're looking into this but in the meantime you can find a workaround here:

Thank you very much!
I wasn't able to find this article on google, maybe because it is too new and it is not indicized yet.

Tried the solution, same issue.  Removed mono-complete, removed emby-server.  Re-installed mono-complete then emby-server.

You might want to double check that thread and compare your procedure to theirs.

I did...I I just realized what's happening.  I need to remove the entire /var/lib/emby-server directory for it to work.  If I restore my config and data folders, it crashes with the error below.  If that's that case, If I can just recover my watched status, I'll be ok rebuilding everything from scratch.  Hell, that's the reason I started to use Emby anyway, to sync watch status between my Kodi devices.

   Access to the path "/var/lib/emby-server/config/encoding.xml" is denied.

 

 

chown -R emby:emby /var/lib/emby-server

 

 

should fix your error with your backup

That fixed it!  Thanks.

 

I think this migration docs needs to be updated to include Linux data.
