换源

（1）编辑sources.list文件

sudo gedit /etc/apt/sources.list

（2）更换清华源
打开文件后，直接删除之前的文件，把下面的粘上去

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main universe restricted
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main universe restricted

3）更新源

sudo apt-get update

添加中文输入法
安装ibus-pinyin

sudo apt-get install ibus-pinyin

安装完成后

ibus-setup

切换到输入法选项卡，点击添加按钮，选择汉语，有两个选项，选择Pinyin

python2,3切换
终端输入python，打开的是python2，不是python3

which python3

查看安装python的目录：/usr/local/bin/python3
打开/usr/bin

cd /usr/bin 

移除之前的链接

rm python

建立与python3的软连接

sudo ln -s /usr/local/bin/python3 /usr/bin/python

最后

reboot

重启
