You will have to install the above packages yourself.
このパッケージを直接インストールする必要がありますが、どうすればよいですか？
試してみると、sudo apt-get install <some_package>次のメッセージが表示されます（例：gcc-4.8-multilib）。
gcc-4.8-multilib : Depends: lib32gcc-4.8-dev (= 4.8.2-19ubuntu1) but it is not going to be installed
Depends: libx32gcc-4.8-dev (= 4.8.2-19ubuntu1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
誰かがこれらすべてのパッケージのインストールの問題を解決するのに役立ちますか？

端末を開き、次のように入力します。
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoclean ローカルリポジトリから取得したパッケージファイルを消去します/var/cache/apt/archives。違いは、もはやダウンロードできず、本質的に役に立たないパッケージファイルのみを削除することです。
sudo apt-get autoremove他のパッケージへの依存関係を満たすために自動的にインストールされたが必要なくなったパッケージを削除するために使用されます。
autocleanまた、autoremoveシステムに影響を与える可能性のある不要なソフトウェアパッケージがないことを確認するためにも使用されます。
sudo apt-get updateソースリストを更新し、ソースのパッケージインデックスファイルを再同期します。
sudo apt-get dist-upgradeアップグレード機能を実行することに加えて、dist-upgradeはソフトウェアパッケージの依存関係の変更をインテリジェントに処理することもできます。
