“不是目录”错误

Question

刚刚在我的笔记本电脑上安装了 Lubuntu。Win8 是其上唯一的早期操作系统。

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/

但我不能，因为在 CD 和 dpkg 命令不起作用后发生了一些“不是目录”错误。

这是来自我的终端（奇怪的是它可以识别“ls”命令并带来文件夹，但它不会对键入的甚至复制的路径执行相同的操作！）

none0@none0-X102BA:~$ cd ~/Downloads/slimjet_amd64.deb
bash: cd: /home/none0/Downloads/slimjet_amd64.deb: Not a directory
none0@none0-X102BA:~$ ~/Downloads$ ls
bash: /home/none0/Downloads$: No such file or directory

The program 'rr' is currently not installed. You can install it by typing:
sudo apt install rr

Answer 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

系统将要求您输入密码。当您输入密码时，终端上不会显示任何内容。这个是正常的。

卸载

如果您不喜欢该软件并想要卸载它，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，单击“删除”按钮将其删除。

无论哪种情况，您都需要输入密码。

请参阅如何卸载软件？有关在 Ubuntu 中卸载软件的更多信息。

希望这可以帮助
