Media getting removed from library after update to 4.3.1.0

[maxxoverclocker 5]

After updating to 4.3.1.0 upon starting the service, emby immediately began removing content from my library alongside with errors similar to:

 

• Error App: Error in MusicAlbumResolver resolving /mnt/nas/media/Music/Tycho
• System.IO.FileLoadException: System.IO.FileLoadException: Could not load file or assembly 'MediaBrowser.Model, Version=4.3.1.0, Culture=neutral, PublicKeyToken=null'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

 

I think it's an issue with the update mechanism because the emby service still shows it was started with v4.3.0.30 (dashboard reflects this as well). The paths listed in the 'resolving' errors all exist and are accessible.

 

I gathered the embyserver logs before I restored from snapshot, but can try replicating this again if needed.

How weird, I swear I attached the logs. Let me try again.

 

embyserver.7z

 

Ha. Yeah, I just don't know how to click buttons apparently. See attached.

The reason for your problem is due to installing 4.3.1 and then rolling back to 4.3.0.30. I would just go back up to 4.3.1.

On linux we don't have any auto-update mechanism. How did you update?

Hmm, I never did a rollback (manually). I'm using the recommended dpkg command:

 

dpkg --install /mnt/nas/home/local/emby/emby-server-deb_4.3.1.0_amd64.deb

 

Update logs look normal to me:

Can you try doing it again? thanks.

Ha. I ran it again and the logs are completely clean and no media is getting removed. No idea... I use an automated rundeck job to install updates and the procedure looks clean on both the one that failed and the one that succeeded. No process difference here... Only difference was the ubuntu server running emby had an uptime of 2 weeks before I ran the update the first time.

 

Thanks for the help.
