Current Behavior

Upon updating to lscr.io/linuxserver/plex:1.42.2 my container began crash looping with exec /init: exec format error.

Expected Behavior

I would update to 1.42.2 and it would behave the same as 1.42.1.

Steps To Reproduce

1. Run Plex of any other version, ie. 1.42.1
2. Update to this image's 1.42.2 or latest tags
3. Plex no longer functions

I confirmed that rolling my setup back to 1.42.1 allowed Plex to start up like normal again. So I'm guessing a critical binary in this Plex container's entrypoint was only built for arm64.

Environment

I run Plex in Kubernetes, using containerd 1.7.29 as the CRI. Base OS is Ubuntu 24.04, kernel 6.8.0-90-generic. The node is amd64.

CPU architecture

x86-64

This error can also manifest on a corrupted download of the image. Please remove it from the containerd storage, and pull it again.

@Roxedus you nailed it. I'd have expected the CRI to fail to start the container if the image were corrupted, I guess 😅 But after rm-ing the image and pruning from all my nodes, Plex 1.42.2 started right up.
