Debian 13 not supported?

[TugboatBill 16]

I upgrade to the latest release and I see in the service startup:
Aug 01 11:13:33 Emby sh[1632]: /bin/sh: /opt/emby-server/lib/libc.so.6: version `GLIBC_2.38' not found (required by /bin/sh)

Aug 01 11:13:33 Emby sh[1632]: /bin/sh: /opt/emby-server/lib/libc.so.6: version `GLIBC_2.33' not found (required by /bin/sh)

Aug 01 11:13:33 Emby sh[1632]: /bin/sh: /opt/emby-server/lib/libc.so.6: version `GLIBC_2.34' not found (required by /bin/sh)

And of course the service fails to start.  This is on Debian 6.12.94-1 (2026-06-20) x86_64 (not docker)
I saw this trying to upgrade from 4.9.3.0 to 4.9.4.0 and to 4.9.5.0

Hi there, I can't reproduce on a fresh Debian 13 VM. Are you using systemd to run the service? Do you have LD_LIBRARY_PATH set in /etc/conf.d/emby-server.conf? If so, try removing it, that file should not set LD_LIBRARY_PATH.

[TugboatBill 16]

Yes, I'm using systemd.  I don't have the /etc/conf.d folder.  I do have /etc/emby-server.conf and /etc/init/emby-server.conf.  Neither have LD_LIBRARY_PATH defined though.  

[alucryd 340]

Did you modify the service in any way? Using systemctl edit for example? This can only happen if our LD_LIBRARY_PATH is already present in the environment when systemd runs our launcher script.

@TugboatBillMight have found a way to stop depending on LD_LIBRARY_PATH, would you give a test build a try?

My emby server is a proxmox VM that has a nvidia card passed through to it (for transcoding).    I have several NAS that I have NFS shares on that I mount to the emby server.  I've had issues with the server not seeing the nas for various reasons and so I have a script - /usr/local/bin/check-nfs-before-emby.sh (seen in the systemctl status for the service below) that ensures the shares are mounted before  emby server starts and emails me if there's a problem. It doesn't use  LD_LIBRARY_PATH.  That is first in the startup of the service.  Next is a conf (90-nvenc.conf below) that sets up for ffmpeg.  It was added as I couldn't get the NVIDIA card to transcode properly (wasn't finding the right ffmpeg files).  I used a AI chatbot to come up with the following::
 

[Service]
# Sets the library path so Emby's bundled FFmpeg can find its dependencies
# and the necessary Intel (libmfx) and NVIDIA libraries.
Environment="LD_LIBRARY_PATH=/opt/emby-server/lib:/opt/emby-server/extra/lib"

# Add a short delay to ensure the NVIDIA device files are fully initialized
# before Emby attempts its hardware detection. This can fix timing issues.
ExecStartPre=/bin/sleep 5

The service (systemctl status emby-server):

alucryd - I could give it a try if you think the additional stuff I just posted doesn't change the situation.
