Ubuntu 15.10ソフトウェアセンターは、起動後すぐに閉じます

私はちょうどUbuntu 15.10をインストールしました（Linuxの一般的な初心者、btw）。ソフトウェアセンターとubuntuアップデータアプリケーションは、開いた直後に閉じるようです。端末は、ソフトウェアセンターの起動に対して次の反応を思い付きました。

これは私のような人にとっては情報が多すぎます。誰かが私のマシンに何が起こっているのかを解釈してもらえますか？

PS：ソフトウェアアップデーターを開く前に、spotifyソフトウェアをダウンロードしようとしていました。それは失敗し、理由はわかりません。多分それはあなたが見るものに役割を果たす...

ありがとう！カイザー

次のようなコマンドを使用して、/etc/apt/sources.list.d/spotify.listでファイルを開きます。

gksudo gedit /etc/apt/sources.list.d/spotify.list

ファイル内の現在の行（少なくともSudoで始まる行）をクリアします。

これを追加：

deb http://repository.spotify.com stable non-free

実行（これはspotifyソフトウェアソースを信頼します）：

Sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys BBEBDCB318AD50EC6865090613B00F1FD2C19886

次に実行します（これにより、使用可能なソフトウェアのリストが更新されます）。

Sudo apt-get update

最後に、実行します（コマンドラインを使用してspotifyをインストールします。この時点で、これも実行できるソフトウェアセンターが必要だと思います）。

Sudo apt-get install spotify-client
