はじめに
Ubuntu 22.04 では Ubuntu 22.04 (WSL) に Dockerをインストール のように行いましたが、24.04 にインストールするにあたって再度、公式手順に従って行いました。
実際に行った内容
インストール
sudo apt-get update sudo apt-get install ca-certificates curl
下記は、ディレクトリは既に存在しているため、省略しました。
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc sudo chmod a+r /etc/apt/keyrings/docker.asc
echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \ $(. /etc/os-release && echo "${UBUNTU_CODENAME:-$VERSION_CODENAME}") stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
確認

dockerグループにユーザを追加します。
$ sudo usermod -a -G docker ${USER}
docker container ls コマンドを実行して、下記のメッセージが出るようであれば、OS(WSL)を再起動します。
$ docker container ls permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdocker.sock/v1.46/containers/json": dial unix /var/run/docker.sock: connect: permission denied
