docker: "specify mac-address per network" requires API version 1.44, but the Docker daemon API version is 1.43.

you can try updating Docker using this command:

wget -qO- https://get.docker.com/ | sh

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

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

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

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


apt upgrade docker-ce

systemctl enable --now docker

./launcher rebuild app
