Problema dopo l'aggiornamento di Docker: errore versione non supportata

Supporto
1

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?

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

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:

  1. 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

  2. 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
