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:
```bash
docker --version
```
### 2. **Update the Operating System**
Make sure the operating system is up-to-date:
```bash
sudo apt update && sudo apt upgrade -y
```
### 3. **Uninstall the Old Version of Docker (if necessary)**
Remove any existing version of Docker:
```bash
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:**
2. **Install Docker:**
### 5. **Verify the Installed Version**
Check if the new version has been installed:
```bash
docker --version
```
### 6. **Restart Docker Services**
After installation or upgrade, restart the Docker service:
```bash
sudo systemctl restart docker
```
### 7. **Update Discourse**
Once Docker is updated, try updating Discourse again:
```bash
cd /var/discourse
./launcher rebuild app
```
