yum install でrepositories failedのエラー

AmazonLinux_CentOS,EC2,OperatingSystem

症状

  • Red Hat, CentOS, Amazon Linux にて、yumリポジトリへの接続ができない場合、yum list やyum install コマンドがエラーとなります。
  • 今回下記のエラーを経験しました。原因は"repo-server" 障害のため、リポジトリの参照ができませんでした。
# yum install install-to-package

 One of the configured repositories failed (Offline Repository),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=repo-id1 ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable repo-id1
        or
            subscription-manager repos --disable=repo-id1

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=repo-id1.skip_if_unavailable=true

failure: repodata/repomd.xml from repo-id1: [Errno 256] No more mirrors to try.

対処方法

  • 一時的にリポジトリを無効にしてインストールを行います。repoファイルは編集しないため、作業後は特に戻しは必要ありません。
  • 先ず、"repo id" を確認するため、yum repolist を実行します。次に、repo id を指定、障害のあるリポジトリを一時的に無効化して、パッケージをインストールします。
# yum repolist
← "repo id" を確認する

# yum install install-to-package --disablerepo=repo-id1,repo-id2
← 特定したrepo idを指定、無効化してパッケージをインストールする
