我是 Ubuntu 新手，我一直尝试按照说明安装 Firefox 开发者版本，但它一直在安装 Firefox 48。
sudo add-apt-repository ppa:ubuntu-mozilla-daily/firefox-aurora
sudo apt-get update
sudo apt-get install firefox
这些是我一直在做的步骤。我只是收到一条消息说 Firefox 已经是最新版本了。
但是，当我执行以下操作时，我看到列表中有版本 50.0
sudo apt-cache madison firefox

firefox | 50.0~a2~hg20160909r333109-0ubuntu1~umd1~trusty | http://ppa.launchpad.net/ubuntu-mozilla-daily/firefox-aurora/ubuntu/ trusty/main Sources
我是新手，我猜我做错了什么或误解了什么。你能帮忙吗？谢谢。

检查 PPA 后，我发现版本 50 的可信版本二进制构建在所有架构上都失败了。这意味着还没有版本 50 的二进制包。参见此处https://launchpad.net/~ubuntu-mozilla-daily/+archive/ubuntu/firefox-aurora/+packages?field.name_filter=&field.status_filter=published&field.series_filter=trusty. 检查构建状态。
这就是你无法安装它的原因。你需要等到它修好或者自己动手安装。
