每当我尝试sudo apt update这样做时，都会出现此错误并退出，我不记得两周前通过终端安装 sublime text 的方式，有没有办法解决这个问题

Answer 1

删除过时的 PPA

webupd8 PPA 自 2018 年以来一直没有更新，并且不支持 Ubuntu 20.04。

将其删除

sudo add-apt-repository --remove ppa:webupd8team/sublime-text-2

从其官方存储库安装 Sublime Text 4

安装 sublime text 的说明可以在其网站上找到。

首先，安装 GPG 密钥：

wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -

然后在apt中启用https源

sudo apt-get install apt-transport-https

对于稳定版本，输入命令

echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list

更新 apt 索引并安装 Sublime Text

sudo apt update
sudo apt install sublime-text
