スナップを作成し、実行してローカルにインストールしました
$ snap install <filename> --dangerous
プラグを追加し始めるまではうまくいきました。
「スナップ リスト」を実行すると、次のエラーが発生します。
error: cannot list snaps: cannot communicate with server: Get http://localhost/v2/snaps: dial unix /run/snapd.socket: connect: connection refused
snapd が実行されていないため、問題のスナップを削除したり、何もすることができません。これは16.04 Ubuntu上にあり、ビルドツールがインストールされています。
コマンド「journalctl -u snapd.service」を実行すると、次の出力が得られます。

snap/snapd システムの動作に戻りたいです。私のスナップのプラグ 'home' または 'network-bind' が原因で、snapd がクラッシュするようです。再起動すると、これが再び行われます。このインストールされたスナップを削除するにはどうすればよいですか? それとも新しく始めますか？
