ubuntu16.04更換成國內源

一、首先使用自帶的vi編輯器

安裝完ubuntu后沒有默認的root密碼，如果要設置root密碼需要進行如下步驟：

1 sudo passwd

2 連續輸入兩次新密碼

二、vi編輯器下使用【backspace】無法刪除

1.

先找到vimrc.tiny文件，一般路徑是  

cd   /etc/vim/

 

 

 

2.

由於vimrc.tiny文件需要用到root權限修改，所以要使用

sudo gedit    vimrc.tiny 

命令，在gedit里修改

3.

把原來的

set compatible

替換成

set nocompatible
set backspace=indent,eol,start

如下圖所示

 

 

 然后就可以進行絲滑的刪除操作啦~

三、開始進行替換源操作，參考鏈接為：https://blog.csdn.net/wzyaiwl/article/details/88571414

Ubuntu16.04默認是國外的源，這非常容易造成我們下載速度的緩慢。接下來，我們將其更換成國內阿里的源。

1. 復制本地源到另一個文件
2. 更換源
3. 更新源
4. shell腳本

復制本地源到另一個文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

更換源

用vi打開sources.list文件，將里面的內容換成下面。

deb http://mirrors.aliyun.com/ubuntu/ xenial main

deb-src http://mirrors.aliyun.com/ubuntu/ xenial main

 

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main

 

deb http://mirrors.aliyun.com/ubuntu/ xenial universe

deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe

deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe

 

deb http://mirrors.aliyun.com/ubuntu/ xenial-security main

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main

deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe

deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe

更新源

更新軟件包列表

sudo apt-get update

休復損壞的軟件包，嘗試卸載出錯的包，重新安裝正確版本的。

sudo apt-get -f install

升級系統中的所有軟件包

sudo apt-get upgrade

腳本

在當前家目錄下，將要使用的源保存在sources.list文件中。

# 更換國內源（使用的是阿里的源）

#sourcesfile=/etc/apt/sources.list.old

#if [ ! -e "$sourcesfile" ]; then

#    echo 'backups sources.list'

#    sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

#    sudo cp $HOME/sources.list /etc/apt/sources.list

#fi

 

# 軟件更新

sudo apt -y  update   # 更新源

sudo dpkg --configure -a

sudo apt -y  upgrade  # 更新已安裝的包

sudo apt -y  dist-upgrade  # 升級系統

# 注意以上安裝過程中出現的安裝選項，直接回車或者選擇yes即可

sudo apt-get -y  autoremove

sudo apt -y autoclean
