■ skip-brokenとは・・・

skip-brokenとはrpmパッケージのアップデート時に依存関係のパッケージの不具合等でアップデートできない場合に利用すると便利です。
例えばパッケージ一括アップデート時に、一つでもエラーがある場合は全くアップデートできません。
しかし、この「skip-broken」を利用すれば、問題があるパッケージを除いて全てをアップデートする事が可能になります。

■ yum plugin「skip-broken」のインストール

「skip-broken」のインストール # yum -y install yum-skip-broken

■ 「skip-broken」の利用方法

■ 利用方法

プラグインを使用するにはyumオプションに「--skip-broken」を付与します。 例) # yum --skip-broken update

■ 動作例

現在、アップデート可能なパッケージを確認 # yum check-update Loading "fastestmirror" plugin Loading "downloadonly" plugin Loading mirror speeds from cached hostfile * fedora: ftp.riken.jp * updates: ftp.riken.jp fedora
