我正在尝试在我的冗余笔记本电脑上安装 docker，但问题是无论我在终端做什么都会遇到这个错误：W: Unable to read e - open (2: No such file or directory)
这是我的终端的输出：
dennis@Titan:~$ sudo apt update

W: Skipping acquire of configured file 'stable/source/Sources' as repository 'https://download.docker.com/linux/ubuntu focal InRelease' does not seem to provide it (sources.list entry misspelt?)
dennis@Titan:~$ sudo list -a docker -ce

dennis@Titan:~$ sudo apt list -a docker -ce

有人能告诉我到底出了什么问题吗？我已经检查过 /var/lib/apt/lists/partial 文件夹已经存在并且是空的。
我是否在前面使用 sudo 并不重要，所以我猜这也不是与管理员帐户相关的问题。
