刚刚在我的笔记本电脑上安装了 Lubuntu。之前它只运行过 Win8 操作系统。
之后我尝试按照以下步骤安装slimjet：
https://linuxways.net/ubuntu/how-to-install-slimjet-browser-on-ubuntu-20-04/
但我无法做到，因为 CD 之后出现了一些“不是目录”错误，并且 dpkg 命令不起作用。
这是从我的终端获得的（奇怪的是，它可以识别“ls”命令并带来文件夹，但它不会对键入或甚至复制的路径执行相同的操作！）

The program 'rr' is currently not installed. You can install it by typing:
sudo apt install rr
答案1
该页面上的说明是错误的！
正确的命令是：
cd ~/Downloads
cd代表更改目录。Downloads是目录。
完成上述命令后，输入下一个命令：
sudo dpkg -i slimjet_amd64.deb
系统会要求您输入密码。输入密码后，终端上不会显示任何内容。这是正常现象。
卸载
如果你不喜欢该软件并且想要卸载它，请使用以下命令：
sudo apt remove slimjet
另一种卸载方法是打开 Ubuntu 软件商店并搜索 slimjet。它应该被列为已安装的软件，然后单击消除按钮将其删除。
无论哪种情况，您都需要输入密码。

您无法通过 cd（更改目录）转到 .deb 文件，因为它不是目录。
请尝试执行sudo dpkg -i ~/Downloads/slimjet_amd64.deb以安装位于下载目录中的 slimjet_amd64.deb。
