国内有很多Ubuntu的镜像源,包括阿里的、网易的,还有很多教育网的源,比如:清华源、中科大源。
我们这里以清华源为例讲解如何修改Ubuntu 18.04里面默认的源。
第一:备份源文件cd /etc/apt/
然后输入ls
会显示下面的源文件 sources.list
输入命令
sudo cp sources.list sources.list.bak
就是将sources.list备份到sources.list.bak
第二步:替换源文件((操作前请做好相应备份):)清华大学源
sudo gedit sources.list
终端输入上述命令打开文件,并删除文件中的全部内容,将下面的代码粘贴进入文件中。
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
3、修改完成后,保存文件,警告什么的都不理,然后运行下面的命令。
sudo apt-get update
sudo apt-get upgrade
4、到此完成国内源更新。
附加其他源内容,需要的自己添加进sources.list文件里面就ok了。

Ubuntu 18.04 在系统设置里面是找不到软件源设置界面按钮的(找了好久都没找到T-T),所以需要一些指令帮助启动图形界面以便设置软件源。
1、输入命令
sudo update-manager -c -d
2、会弹出Software Updater提示框,这就好办了,点击左下角Settings…按钮,久违的软件源设置就会出来啦。
3、那就开始愉快地设置软件源吧!
