Resolution
この問題は、Bugzilla 1096734 - AttributeError: 'exceptions.ValueError' object has no attribute'msg' でエンジニアリングチームが対応しています。
修正は RHEL 6.5 (python-rhsm bug fix update) で利用でき、RHEL 6.6 に含まれることが予定されています。
サードパーティの CA 証明書がシステムに設定されているプロキシサーバーがネットワークに存在せず、依然としてこの問題が発生している場合は、以下の手順が回避策として使用できます。
# subscription-manager unregister
# subscription-manager clean
# subscription-manager register
# subscription-manager list --available
# subscription-manager subscribe --pool=pool-id
もしくは、上述のようにシステムを登録した上で、カスタマーポータルからサブスクリプションを登録します。
Root Cause
- クライアントシステムと Red Hat Network との間のプロキシサーバーがサードパーティの SSL CA 証明書を使用しています。
- 以下のコマンドから返された SSL サーバーの証明書を確認すると、これを確認できます。予想される Red Hat Network 証明書の対象者と発行者は以下のようになります。
# openssl s_client -connect subscription.rhn.redhat.com:443
