Hi! I ran into the same problem after upgrading to Docker 29.1.0. Unbound doesn’t seem to like it. The solution was to downgrade Docker back to 29.0.4. This command did the trick on my Ubuntu server:
sudo apt install docker-ce=5:29.0.4-1ubuntu.24.04noble \
docker-ce-cli=5:29.0.4-1ubuntu.24.04noble \
docker-buildx-plugin \
docker-compose-plugin \
containerd.io
I also disabled updates for Docker until this is solved:
sudo apt-mark hold docker-ce docker-ce-cli docker-buildx-plugin docker-compose-plugin containerd.io
It would be great to know what exactly cause Unbound to stop working and if there’s an official fix other than holding back Docker updates.
Best,
-T.
