Let me share my solution  
The problem is that Docker 28.x is not available in Ubuntu 24.04.3 LTS’s official package list.

```plaintext
cd /var/discourse
git pull origin main --autostash

```

```plaintext
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

```

```plaintext
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
  https://download.docker.com/linux/ubuntu noble stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

```

```plaintext
apt upgrade docker-ce

```

```plaintext
systemctl enable --now docker

```

```plaintext
./launcher rebuild app

```
