我昨天更新到了 ubuntu 12.04。并使用以下命令安装 juju：
sudo add-apt-repository ppa:juju/pkgs
sudo apt-get update && sudo apt-get install juju
我也安装了 lxc，然后部署了 charms，但服务没有启动，日志显示 python 错误。

顺便问一下，我在machine-agent.log中发现很多安装日志，第一次安装正常吗？
谢谢。

这是一个合法的错误，表示在构建最小 ubuntu 时下载这些软件包失败。在这种情况下，您可能需要删除缓存的引导系统：
sudo rm -rf /var/cache/lxc/precise
然后重试。确保您可以访问archive.ubuntu.com，因为这是用于下载软件包的。
