 Error: Cannot find a valid baseurl for repo: extras

!!対処法

サポートが終了したバージョン([FC6は2007年に終了している|http://typea-mixi01.appspot.com/yh_s?q=Fedora+Core+6+EOL])でもyumは使える。最低でも、アーカイブされている最終バージョンは利用できるみたい。

!手順
::/etc/yum.repos.d ディレクトリにある、.repoファイルについて、以下を行う
'''1.baseurl行のコメントアウトをはずして、アーカイブのURLに書き換える'''
""baseurl=http://archive.fedoraproject.org/pub/archive
'''2.mirrorlist行をコメントアウトする'''

!実践
自分の環境では、以下が存在している・・・
 fedora-core.repo
 fedora-development.repo
 fedora-extras-development.repo
 fedora-extras.repo
 fedora-legacy.repo
 fedora-updates-testing.repo
 fedora-updates.repo

とりあえず、めぼしいやつを修正
