Ubuntu 18 更新失败

Update failure in Ubuntu 18

我想尝试用 sudo apt-get update 更新我的 Ubuntu 18。但最后它显示了该消息。

您还需要什么吗?抱歉,我是 Ubuntu

的新手

看起来这个 ppa 不支持 Ubuntu 18.04。 404 是一个 http return 代码,表示无法找到所请求的页面。此外,如果您检查 url http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu/dists/。我找不到 bionic 的文件夹,而且最后一次更新时间戳是 68 周前,所以现在不支持。

但是 sublime text 支持自己的 ppa,所以只需使用 this guide how to install sublime text on ubuntu 18.04.
