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
