错误:打开缓存(E:在源列表/etc/apt/ source .list.d/r-ran.list第1行中不知道'sudo‘类型

Question

我正在尝试安装R。我在一个以前的职位上尝试了最佳答案的说明，但没有成功。我使用的是ubuntu 16.04.6 LTS 64位。

我尝试了这个方法，但是我的终端窗口似乎什么也没做，即使当我试图关闭窗口时，它说有进程在运行。我试过几次。现在，我在上面的薄薄的灰色托盘上有一条错误信息：

An error occurred, please run the package manager from the right-click menu or apt-get in a terminal to see what is wrong. 

错误信息是：

Error: Opening the cache (E:type 'sudo' is not known on line 1 in source list /etc/apt/sources.list.d/r-cran.list,   
E:The list of sources could not be read.)

This usually means that your installed packages have unmet dependencies.

启动包管理器(通过通知)没有做任何事情，我收到了以下消息(图像附件)：

E: Type 'sudo' is not known on line 1 in source list/etc/apt
sources.list.d/r-cran.list  
E: The list of sources could not be read. Go to the repository dialogue to correct the problem.  
E:_cache->open()failed, please report. 

我不知道如何进入存储库，也不知道如何报告。我该如何解决这个问题？

我还尝试了此链接上的说明，复制源代码并粘贴到终端，这可能不是如何做到这一点，但我不知道如何访问/etc/apt/sources.list文件。

@heynnema，当我运行代码时，它写着cat: /etc/apt/ such es.list.d/r-ran.list:没有这样的文件或目录

@heynnema --补丁没有工作--这里是终端的输出：

@heynemma这里是cat /etc/apt/sources.list.d/r-cran.list的结果

helwalaura@卡拉狄加：~$ cat /etc/apt/sources.list.d.list.d/r-ran.list

sudo tee /etc/apt/sources.list.d/r-cran.list
sudo cat <

@heynnema当我删除另外两行代码时，它出现在终端窗口中：

Answer 1

为了收拾残局，我们会从一开始.这应该让你开始..。使用复制/粘贴与下列行，因为其中有些是非常长.

注意:一些/所有这些"R“包都在Ubuntu19.10存储库中。

在terminal..。

sudo -H gedit /etc/apt/sources.list.d/r-cran.list

把这个作为文件中唯一的一行.

deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran35/

保存文件并退出gedit。

在terminal..。每次复制/粘贴一个命令到terminal中.第一个命令很长..。

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo apt-get update
sudo apt-get install r-base r-base-dev

Update #1:

剩菜..。但很容易解决..。

sudo -H gedit /etc/apt/sources.list

转到gedit prefs，并启用行号。

转到文件的末尾(第52行)，您可能会发现这样的一行.

deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran35/

删除那一行。保存文件并退出gedit。

sudo apt-get update
sudo apt-get install r-base r-base-dev

我们应该完蛋了！
