[BUG] 1.41.0.8994-f2c27da23-ls237 release is not working on Raspberry Pi5

[matzarah]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Container produces the following error on start:

Starting Plex Media Server. . . (you can ignore the libusb_init error)
s6-applyuidgid: fatal: unable to exec /usr/lib/plexmediaserver/Plex Media Server: Exec format error

I do not experience the problem with the exact same image on Raspberry Pi4, both are running 64 bit OS.

The previous container (1.41.0.8992-8463ad060-ls235) worked fine.

Expected Behavior

No response

Steps To Reproduce

On a Raspberry Pi 5 running 64bit, execute:
docker run --rm -it linuxserver/plex:latest

Environment

- OS: Debian GNU/Linux 12 (bookworm)
- Arch: 6.6.47+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.47-1+rpt1 (2024-09-02) aarch64 GNU/Linux
- How docker service was installed: from docker.com install instruction

CPU architecture

arm64

Docker creation

run --rm -it linuxserver/plex:latest

Container logs

Starting Plex Media Server. . . (you can ignore the libusb_init error)

I am getting this error too, but with nvidia-smi on the same version.

I tried to copy out nvidia-smi so I could find out what arch it is for, but ran into problems getting out the file. It pulls out as 0 kb for whatever reason.

Working fine here

When I do the same, I don't get any output.

# docker-compose exec pms-docker bash
root@plex:/# nvidia-smi
root@plex:/#

my docker-compose file is

name: plex
services:
  pms-docker:
    restart: unless-stopped
    container_name: plex
    runtime: nvidia
    deploy:
      resources:

      - /transcoding/:/transcoding
      - /tv:/tv
    image: lscr.io/linuxserver/plex:latest

And this has worked forever. Last night, I noticed nobody watching on my server was transcoding. I have tried many things: reinstalling container tools, verifying it works through Ubuntu images, etc... it is seemingly specific to the linuxserver image.

Here's what I found since my last post.

• There is an nvidia-smi file at /usr/local/bin/nvidia-smi, but it is 0 bytes. How does this file get populated?
• I copied my nvidia-smi to the local container. Now, I can see errors like:

root@plex:/# nvidia-smi
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.

The Nvidia components of the container are not getting added correctly. This does seem like a separate issue than what this issue was created for since my Plex Media Server binary starts after updating, but maybe there's a related root cause as to why OP's binary is having the same error.

[Roxedus]

nvidia-smi: exec format error

This not remotely the same error. You seem to have a issue with the Nvidia container runtime.

[Roxedus]

@matzarah does it work if you specify the architecture in your command?

[didyouexpectthat]

You seem to have a issue with the Nvidia container runtime.

Thanks. I will go back down this route. I did try reinstalling it as a troubleshooting step from their website.

/usr/lib/plexmediaserver/Plex Media Server: Exec format error
nvidia-smi: exec format error
This not remotely the same error.

My apologies; they appear similar.

@Roxedus it didn't, but I see there is since a new image and that is working OK
