Ubuntu 18中的更新失败

Question

我想尝试用sudo apt-get update更新我的Ubuntu 18。但最终它表明了这一信息。

您还需要别的什么吗？抱歉，我是Ubuntu的新手

看起来这个ppa不支持Ubuntu18.04。404是一个http返回代码，意味着无法找到所请求的页面。另外，如果您检查url http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu/dists/。我找不到一个文件夹的仿生，而且最后的更新时间戳是68周前，所以这是不支持现在。

但是崇高文本支持自己的ppa，所以只需使用本指南如何在ubuntu18.04上安装崇高文本。
