Grails 安装错误：Err http://ppa.launchpad.net saucy/main amd64 Packages 404 Not Found

我曾尝试使用在以下位置找到的答案来安装 Grails安装 Grails 时出错 - 未满足依赖关系：

sudo add-apt-repository ppa:groovy-dev/grails  
sudo apt-get update
sudo apt-get install grails-ppa

第一个命令没有错误地返回：

$ sudo add-apt-repository ppa:groovy-dev/grails

知道为什么 ppa 更新失败并出现 404 错误吗？

答案1

Ubuntu 13.10 不再受支持，因为它的使用寿命已到尽头。
您应该升级到 14.04 或使用 12.04（当前支持的 LTS 版本）以获取最新的（安全）升级。

您收到 404 错误是因为 ppa 不再维护，很可能是因为 13.10 的 eol。
