Current Behavior

Upgrading from latest docker lscr.io 2025.4 image to 2025.5 breaks some integration.

Expected Behavior

Integration still work after upgrade.

Steps To Reproduce

Upgrade from 2025.4 to 2025.5 lscr.io image

Environment

- OS: Synology DSM

CPU architecture

x86-64

Docker creation

Docker compose:
 
homeassistant:
  container_name: homeassistant
  image: lscr.io/linuxserver/homeassistant:latest
#  image: lscr.io/linuxserver/homeassistant:2025.4.4-ls101
  environment:
  - PUID=1026
  - PGID=65540
  - TZ=Europe/Paris
  - DOCKER_MODS=linuxserver/mods:homeassistant-hacs
  volumes:
  - /volume2/docker/homeassistant:/config
  ports:
  - 8123:8123
  restart: unless-stopped
  links:
  - mqtt:mqtt
  cap_add:
  - NET_RAW 

Command to switch from one to the other version `sudo docker-compose -f docker-compose.yml up --force-recreate -d homeassistant`

Which integration is breaking? also could you post the kernel version of your synology?

[9pr19]

@j0nnymoe please find below some information

uname -a
Linux DiskStation 4.4.302+ #72806 SMP Thu Sep 5 13:42:01 CST 2024 x86_64 GNU/Linux synology_apollolake_918+

DSM 7.2.2-72806 Update 3

Similar issue here. Upgrading to 2025.5 broke at least Philips Hue and Sonos integrations, with the same log message as @9pr19 . I'm on Ubuntu 24.04.2 LTS (GNU/Linux 6.8.0-58-generic x86_64).

I rolled back to 2025.4.4 and all started working again as previously.

Looks like an upstream issue
home-assistant/core#144453

[aptalca]

Can you guys confirm the new version works?

[9pr19]

@aptalca I’ve upgraded a few minutes ago to 2025.5.1-ls103 and everything run smoothly now. Thank you for your help.
