`The futex facility returned an unexpected error code` on Raspberry Pi 4 with Ubuntu 24.04

[iamskok]

Describe the bug Running docker compose up -d for Unbound DNS on Raspberry Pi 4 with Ubuntu 24.04 results in the error: The futex facility returned an unexpected error code and core dumps.

To Reproduce Steps to reproduce the behavior:

1. Docker compose file:

   name: dns_stack
   
   services:
     unbound:
       build:
         context: .
         dockerfile: Dockerfile-unbound
       image: "unbound"
       container_name: "unbound"
       hostname: "unbound_1"
       environment:
         TZ: "UTC"
       ports:
         - "5353:5353/udp"
         - "5353:5353/tcp"
       volumes:
         - "/opt/dns-stack/docker/unbound/opt_unbound_etc_unbound/:/opt/unbound/etc/unbound/"
       command: ["/opt/unbound/etc/unbound/unbound.sh"]
       healthcheck:
         test: ["CMD-SHELL", "drill @127.0.0.1 -p 5353 example.com || exit 1"]
         interval: 1m
         timeout: 10s
         start_period: 10s
         retries: 3
       restart: unless-stopped

2. Customizations (config files):

   • unbound.sh:

     #!/bin/bash
     mkdir -p /opt/unbound/etc/unbound/dev
     cp -a /dev/random /dev/urandom /dev/null /opt/unbound/etc/unbound/dev/
     mkdir -p -m 700 /opt/unbound/etc/unbound/var
     chown _unbound:_unbound /opt/unbound/etc/unbound/var
     /opt/unbound/sbin/unbound-anchor -a /opt/unbound/etc/unbound/var/root.key
     curl -o /opt/unbound/etc/unbound/root.hints https://www.internic.net/domain/named.cache
     chmod 644 /opt/unbound/etc/unbound/root.hints
     /opt/unbound/sbin/unbound-control-setup
     exec /opt/unbound/sbin/unbound -d -c /opt/unbound/etc/unbound/unbound.conf

   • Dockerfile-unbound:

     FROM mvance/unbound-rpi:1.19.2
     
     RUN apt-get update && \
         apt-get install -y --no-install-recommends curl && \
         rm -rf /var/lib/apt/lists/*

3. Directory structure:

   /opt/dns-stack/
   ├── docker
   │   └── unbound
   │       └── opt_unbound_etc_unbound
   │           ├── unbound.sh
   │           ├── unbound.conf
   │           └── Dockerfile-unbound
   └── compose.yml

4. Run docker compose up -d
5. See error

Expected behavior Unbound DNS service should start without core dumps or errors, and healthcheck should pass.

Additional context

• Hardware: Raspberry Pi 4
• OS: Ubuntu 24.04
• Docker Image: mvance/unbound-rpi:1.19.2
• Docker Version: 26.1.3

The same setup worked on Ubuntu 23.10 without issues.

[koseduhemak]

facing the same problem at the moment with vanilla image and no additional modifications: Docker Image: mvance/unbound-rpi:1.18.0 OS: Ubuntu 24.04 Docker Version: 26.1.3 Hardware: Raspberry Pi 4

[klaas-sysop]

also the same isue

Docker Image: mvance/unbound-rpi OS: Ubuntu 24.04 Docker Version: 26.1.3 Hardware: Raspberry Pi 5

EDIT 29/05/2024

I tried mvance/unbound-rpi:1.16.0 and it didnot work. so my next step is trying Ubuntu 23.04

EDIT 30/05/2024

Ubuntu 23.04 works perfectly just as iamskok mentioned

[neryencarnacion]

I'm facing the same issue!

Docker Image: mvance/unbound-rpi OS: Ubuntu 24.04 Docker Version: 26.1.4 Hardware: Raspberry Pi 5

[m-ammar]

Any workarounds for this issue? The alternative of downgrading to ubuntu-23.10 is not appealing.

[GreenMonito]

I have the same problem too

Docker Image: mvance/unbound-rpi OS: Ubuntu 24.04 Docker Version: 27.0.3, build 7d4bcd8 Hardware: Raspberry Pi 3B+

Is there a solution for this?, downgrading to Ubuntu 23 is not viable

Thank you so much!
