パッケージ管理システムSnappyとは
Snappyとはカノニカルが設計・開発したパッケージ管理システム。Snappyのパッケージは 'Snap' と呼ばれ、Snapを使うツールは 'Snapd' と呼ばれる。Snapは様々なLinuxディストリビューションで動作するので、ディストリビューションの上流のソフトウェアデプロイメントに依存しない。
snapがプリインストールされたディストリビューション
KDE Neon
Manjaro
Solus 3 and above
Ubuntu 18.04 and above
Most Ubuntu flavours
Zorin OS
snapがプリインストールされていないが利用可能なディストリビューション
各OSごとのインストール方法は下記OSのリンク先で確認してください

参考:公式ドキュメント
LinuxにSnapdをインストール
1. 代表的なLinuxディストリビューションごとのsnapdパッケージのインストール方法
......Debian and Ubuntu......
$ sudo apt update
$ sudo apt install snapd
......Fedora Linux......
$ sudo dnf install snapd
......CentOS & RHEL......
$ sudo yum install epel-release
$ sudo yum install snapd
......openSUSE_Leap_15.0......
$ sudo zypper addrepo --refresh \
![]()
![]()
download.opensuse.org \
snappy
$ sudo zypper --gpg-auto-import-keys refresh
$ sudo zypper dup --from snappy
$ sudo zypper install snapd
2.snapdをインストールした後、メインのsnap通信ソケットを管理するsystemdユニットを有効にする
$ sudo systemctl enable --now snapd.socket
3.起動確認
$ sudo systemctl is-active snapd.socket
active
$ sudo systemctl status snapd.socket
● snapd.socket - Socket activation for snappy daemon

$ sudo systemctl is-enabled snapd.socket
enabled
4./ var/lib/snapd/snapと/ snapの間にシンボリックリンクを作成
$ sudo ln -s /var/lib/snapd/snap /snap
5.snapdおよびsnapコマンドラインツールのバージョンを確認
$ snap version
snap 2.76-0.el9
snapd 2.76-0.el9
series 16
ol 9.8
kernel 6.12.0-205.92.4.2.el9uek.x86_64
architecture amd64
6.パッケージをインストール
例として、Canonical社が開発しているKubernetes環境構築ツールMicroK8sをイントールします
$ sudo snap install microk8s --classic
microk8s (1.35/stable) v1.35.6 from Canonical✓ installed
7.インストールされているパッケージを確認
$ snap list
オプション「--all」で、無効になっているパッケージも表示することができる
$ snap list --all

MicroK8s is a small, fast, secure, certified Kubernetes distribution that installs on just about
any Linux box. It provides the functionality of core Kubernetes components, in a small footprint,
scalable from a single node to a high-availability production multi-node cluster. Use it for
offline developments, prototyping, testing, CI/CD. It's also great for appliances - develop your
IoT apps for K8s and deploy them to MicroK8s on your boxes.
