我已经开发了一个Azure ARM模板来部署Ubuntu Linux机器，一旦配置了bash脚本，它将运行以安装特定的软件。该软件涉及下载一些软件包以及从用户传递输入参数以完成配置。我面临的问题是脚本扩展似乎间歇性地工作。我曾经成功地部署过它，现在它一直都在失败。这是自定义脚本开始执行几秒钟后返回的错误：

下面是我定义扩展名的模板部分

任何人对如何预防此问题或实施必要的更正有任何想法？
答案 0 :(得分：0)
好吧，这清楚地表明：脚本以代码1退出。这意味着脚本本身失败了。因此，您需要登录到vm并查看c：\ windowsazure \ packages \ logs（或类似名称）的扩展日志，找出问题所在，并使用try \ catch逻辑对其进行包装。另外，请考虑将错误传播到控制台，以便您实际上可以在日志中看到它们。

我终于弄清楚发生了什么事。该软件安装具有未自动安装的依赖项，并且正在使整个脚本失败并以status = 1退出。我更改了bash脚本，并在安装过程中手动添加了推荐的依赖项，然后重新部署了模板和booom。安装进行顺利。 这是每个生成的错误消息：
