Hi, I updated Docker through the “Upgrade” section. After that, I tried to update Discourse via the terminal (I use DigitalOcean’s Droplet Console). However, when running the command ./launcher rebuild app, I get this error: ERROR: Docker version 19.03.13 not supported, please upgrade to at least 20.10.0, or recommended 24.0.7. But I had already done the update through the “Upgrade” admin interface on the website. Now nothing is working anymore. What could have gone wrong?

Thank you. The command you provided did not work. I resolved it with the following solution from ChatGPT: To update Docker on a DigitalOcean Droplet, follow these steps: 1. Check the Current Version of Docker Run this command to see the currently installed Docker version: docker --version 2. Update the Operating System Make sure the operating system is up-to-date: sudo apt update && sudo apt upgrade -y 3. Uninstall the Old Version of Docker (if necessary) Remove any existing version of Docker: sudo apt remove docker docker-engine docker.io containerd runc 4. Install the Latest Version of Docker Follow these steps to install the latest version: Add Docker’s Official Repository: sudo apt-get install -y ca-certificates curl gnupg sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null Install Docker: sudo apt update sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin 5. Verify the Installed Version Check if the new version has been installed: docker --version 6. Restart Docker Services After installation or upgrade, restart the Docker service: sudo systemctl restart docker 7. Update Discourse Once Docker is updated, try updating Discourse again: cd /var/discourse ./launcher rebuild app

In the web interface you updated Discourse_docker not docker itself. apt update ; apt install docker-ce Should upgrade docker, I think You can check the version with docker --version
