TypeError: unsubscriptable object

カテゴリ:CentOS

 なんかCentOS5.3でyum updateすると

TypeError: unsubscriptable object

とか表示されてyum update出来ない。って奴は、次のコマンドで救われます。

yum clean metadata

分かるような分からないような感じ。まー、なんかの拍子にmetadataがぶっ壊れたのをcleanしてるのでしょうか。次に「yum update」すると、何事もなかったかのようにupdateが進行します。

 で、manしてみた

yum clean metadata
Eliminate all of the files which yum uses to determine the
remote availability of packages. Using this option will force
yum to download all the metadata the next time it is run.

まー、そのままだよね。なんか、リモートのパッケージ情報がらみをクリアするって書いてあるしなぁ。これ使うと次にyumを走らせたときに、metadataを全部取ってくるとか。やっぱ、metadataが壊れちゃったんでしょう、何かの拍子に。


 ちなみに、エラーメッセージ全容はこんな感じ。
