Ubuntu 16.04でのオクターブ依存関係の問題

新しくインストールしたUbuntu 16.04にオクターブをインストールしようとしています。だから私はこれらのコマンドを試しました：

Sudo apt-add-repository ppa:octave/stable
Sudo apt-get update
Sudo apt-get install octave

「Sudo apt-get update」の後、次のエラーと警告が表示されました。

Err:9 http://ppa.launchpad.net/octave/stable/ubuntu xenial/main AMD64 Packages                                                      
  404  Not Found

  404  Not Found

W: The repository 'http://ppa.launchpad.net/octave/stable/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/octave/stable/ubuntu/dists/xenial/main/binary-AMD64/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

そして、「Sudo apt-get install octave」の後：

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 octave : Depends: libarpack2 (>= 2.1) but it is not going to be installed
          Depends: libcholmod3.0.6 but it is not going to be installed
          Depends: liboctave3 (= 4.0.0-3ubuntu9) but it is not going to be installed
          Depends: libosmesa6 (>= 10.2~) but it is not going to be installed
          Recommends: libopenblas-base but it is not going to be installed or
                      libatlas3-base but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

これらの後、「Sudo apt-get -f install」を試してみると：

ソースコードをコンパイルできるように依存関係をインストールしようとしましたが、同様のエラーが発生しました（Sudo apt-get install libarpack2）：

16.04は新しく、すべてのパッケージがすべてのサーバーで使用できる状態ではありません。メインサーバーを使用してパッケージをダウンロードすると、問題が解決します。

  1. システム設定
  2. ソフトウェアの更新
  3. 「ダウンロード元」セクションから「メインサーバー」を選択します
