Portainer and Docker 29

Portainer was not able to access the local environment with the following error: "Failed loading environment The environment named local is unreachable". Then I found out that it was not compatible with Docker 29. Here are the steps that I used to downgrade Docker to a compatible version.

Downgrade Docker

• Check the version installed
• apt list --installed docker-ce
• Check for available version
• apt-cache policy docker-ce | head -n 30
• Downgrade
• DOCKER_VERSION="5:28.5.2-1~debian.12~bookworm"
• apt-get install docker-ce-cli="$DOCKER_VERSION" docker-ce="$DOCKER_VERSION" docker-ce-rootless-extras="$DOCKER_VERSION"
• Restart
• shutdown -r now
