Snaps は、どこにでもインストールできる「ユニバーサル Linux パッケージ」として販売されています...
Debian 安定版 (stretch) で snapd に問題が発生しているようです。パッケージを削除するのに 3 分かかるなど:
2017-09-09T15:08:29+10:00 ERROR cannot remove snap file "robotica", will retry in 3 mins: snap-robotica-x1.mount failed to stop: timeout
また、スナップが間違った権限でインストールされるというランダムな問題が発生しているようです。
$ ls -l /snap/robotica
total 0
lrwxrwxrwx 1 root root 2 Sep 9 14:32 current -> x7
drwxr-xr-x 8 root root 139 Sep 9 14:03 x5
drwx------ 9 root root 153 Sep 9 14:30 x6
drwx------ 9 root root 153 Sep 9 14:30 x7
Debian の snapd が古いことは理解していますが、unstable の snapd を stretch にバックポートしようとしましたが、次のエラーで失敗します。

それで、これを機能させようとするのは賢明ですか？それとも、損失を減らして今すぐあきらめるだけですか？たぶん、snapcraft は Ubuntu でのみ本当に役に立ちます。
