因为有些设置需要root账号，所以干脆一开始就进入root

sudo -s

STEP1:关于源的更新

问A：为什么要更新源？

答A：

1、因为linux安装软件比较慢，所以更换一些国内的源会加快安装速度

2、由于某些源网址的版本比较老或者没有，可以更新源来获取想要的版本

问B：怎么更新源？

答B：

1、输入下面的命令打开vim编辑器，编辑器会覆盖原来的终端窗口，不用怕，直接粘贴源即可

vim /etc/apt/source.list

2、复制粘贴源（在下面随便选几个源粘贴就好了，我这里选用了阿里云的源）

#阿里云源deb /kali sana main non-free contribdeb /kali-security/ sana/updates main contrib non-freedeb-src /kali-security/ sana/updates main contrib non-free

3、保存并关闭vim编辑器

摁【ESC】然后再输入【:wq】保存并退出

【科普VIM编辑器几个命令行】

:w #write- 写入信息，不退出 vim

:w file #write to file-写入file，不退出 vim

:w! #强制写入，不退出vim

:wq #(write and quite)写入并退出 vim

:wq! #强制写入并退出 vim

:q #(quit)-不写入直接退出 vim

:q! #不写入，强制退出 vim

:e! #(empty)-清空所有操作

4、更新源配置

apt-get update

问C：我们一般用哪些源？

答C：现在比较全以及流行的源有：阿里源，中科大源，清华源和163源等（小知识：deb +网址下载的是deb包，deb-src +网址下载的是deb包的源文件，几乎没差）

Ubuntu apt源阿里源：deb /ubuntu/ bionic main restricted universe multiversedeb /ubuntu/ bionic-security main restricted universe multiversedeb /ubuntu/ bionic-updates main restricted universe multiversedeb /ubuntu/ bionic-proposed main restricted universe multiversedeb /ubuntu/ bionic-backports main restricted universe multiversedeb-src /ubuntu/ bionic main restricted universe multiversedeb-src /ubuntu/ bionic-security main restricted universe multiversedeb-src /ubuntu/ bionic-updates main restricted universe multiversedeb-src /ubuntu/ bionic-proposed main restricted universe multiversedeb-src /ubuntu/ bionic-backports main restricted universe multiverse中科大源：deb https://mirrors./ubuntu/ bionic main restricted universe multiversedeb-src https://mirrors./ubuntu/ bionic main restricted universe multiversedeb https://mirrors./ubuntu/ bionic-updates main restricted universe multiversedeb-src https://mirrors./ubuntu/ bionic-updates main restricted universe multiversedeb https://mirrors./ubuntu/ bionic-backports main restricted universe multiversedeb-src https://mirrors./ubuntu/ bionic-backports main restricted universe multiversedeb https://mirrors./ubuntu/ bionic-security main restricted universe multiversedeb-src https://mirrors./ubuntu/ bionic-security main restricted universe multiversedeb https://mirrors./ubuntu/ bionic-proposed main restricted universe multiversedeb-src https://mirrors./ubuntu/ bionic-proposed main restricted universe multiverse163源：deb /ubuntu/ bionic main restricted universe multiversedeb /ubuntu/ bionic-security main restricted universe multiversedeb /ubuntu/ bionic-updates main restricted universe multiversedeb /ubuntu/ bionic-proposed main restricted universe multiversedeb /ubuntu/ bionic-backports main restricted universe multiversedeb-src /ubuntu/ bionic main restricted universe multiversedeb-src /ubuntu/ bionic-security main restricted universe multiversedeb-src /ubuntu/ bionic-updates main restricted universe multiversedeb-src /ubuntu/ bionic-proposed main restricted universe multiversedeb-src /ubuntu/ bionic-backports main restricted universe multiverse清华源：deb https://mirrors.tuna./ubuntu/ bionic main restricted universe multiversedeb-src https://mirrors.tuna./ubuntu/ bionic main restricted universe multiversedeb https://mirrors.tuna./ubuntu/ bionic-updates main restricted universe multiversedeb-src https://mirrors.tuna./ubuntu/ bionic-updates main restricted universe multiversedeb https://mirrors.tuna./ubuntu/ bionic-backports main restricted universe multiversedeb-src https://mirrors.tuna./ubuntu/ bionic-backports main restricted universe multiversedeb https://mirrors.tuna./ubuntu/ bionic-security main restricted universe multiversedeb-src https://mirrors.tuna./ubuntu/ bionic-security main restricted universe multiversedeb https://mirrors.tuna./ubuntu/ bionic-proposed main restricted universe multiversedeb-src https://mirrors.tuna./ubuntu/ bionic-proposed main restricted universe multiverse————————————————版权声明：本文为CSDN博主「atd_」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。原文链接：/u012152776/article/details/123572629

STEP2：安装依赖包fcitx

apt-get install fcitx

一般会成功，如果出现依赖错误则输入下面的代码

apt-get -f install fcitx

如果还不行，就是源的问题，更换下源再重复这一步

STEP3：到官网下载SOGOU或者其他输入法（记得选择适合自己系统的包）

到包所在的目录下打开终端输入：

dpkg -i+sogo安装包的文件名

STEP4：输入法配置

1、终端输入以下命令进入到输入法配置，这时候可能会提示你安装下config,同意Y,一直下一步即可。

im-config

2、安装完会弹出一个窗口：system configuration select选择name为fcitx,点OK

STEP5:注销电脑账户重新登入

1、主屏幕右上角会出现小键盘logo，则表示安装基本成功

2、点右上角键盘，进入configure设置，左下角摁【+】，搜索SOGOU,然后添加（如果搜不到，取消only那个√应该就可以了），到这一步成功，快捷键CTRL+空格，即可切换到中文输入，之后shift键可自由切换中英文输入。
