我想尝试使用sudo apt-get update更新我的Ubuntu 18。但最后它显示了该信息。

您还需要其他吗？抱歉，我是Ubuntu的新手

该ppa似乎不支持Ubuntu 18.04。 404是http返回代码，表示找不到请求的页面。另外，如果您检查网址http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu/dists/。我找不到用于仿生的文件夹，而且最近的更新时间戳记是68周前，所以现在不支持此更新。

但是sublime文本支持自己的ppa，因此只需使用this guide如何在ubuntu 18.04上安装sublime文本即可。
