重新安装商业软件（例如，石油冲击，钢铁风暴等）

重新安装Ubuntu 12.04后，无法安装商业游戏，例如Oil Rush。 它给出了这个错误： Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-amd64/Packages The requested URL returned error: 401 Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/oilrush/ubuntu/dists/oneiric/main/binary-i386/Packages The requested URL returned error: 401 Some index files failed to download. They have been ignored, or old ones used instead. 我在11.10买了这些游戏，但我之前在12.04安装了这些游戏……我怎么能解决这个问题？
