再次重装了系统，为方便以后再次重装，，，因此将主要步骤记录下来。
1. 更新源
sudo gedit /etc/apt/sources.list
# 阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

# 中科大源
deb https://mirrors.ustc.edu.cn/ubuntu/ focal main restricted
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-updates main restricted
deb https://mirrors.ustc.edu.cn/ubuntu/ focal universe
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-updates universe
deb https://mirrors.ustc.edu.cn/ubuntu/ focal multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-updates multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu focal-security main restricted
deb http://security.ubuntu.com/ubuntu focal-security universe
deb http://security.ubuntu.com/ubuntu focal-security multiverse
进行更新
sudo apt update
sudo apt upgrade
2. 安装git及配置
sudo apt install git
配置github免密传输
ssh-keygen -t rsa
cd ~/.ssh; cat id_rsa.pub;
将输出信息复制到github设置的SSH and GPG keys一栏，添加
git config --global user.email "your email"
git config --global user.name "your name"
2. 安装vim
sudo apt install vim
使用vim一键配置
wget -qO- https://raw.github.com/ma6174/vim/master/setup.sh | sh -x
3. 安装google
到google官网下载安装包，进入文件夹
sudo dpkg -i ***.deb
网易云、vscode、virtualbox、wps等同理
4. 安装shadowsocks
sudo apt install shadowsocks-qt5
sudo vim /etc/shadowsocks.json
格式为
{
"server":"ip地址",
"server_port":端口号,
"local_port":1080,
"password":"密码",
"timeout":600,
"method":"加密方式"
}
修改网络代理设置
为便于使用，编写脚本
vim .shadowsocks.sh
文件内容为：
#!/bin/sh
sudo sslocal -c /etc/shadowsocks.json
使用时直接运行脚本即可。
5. 安装搜狗输入法
sudo apt install fcitx
官网下载对应的deb包，进入文件夹
sudo dpkg -i ***.deb
进入到Add input method界面，将下面的Only Show Current Language 取消掉后，在搜索栏搜索搜狗拼音，选中之后进行添加。
添加成功后，将搜狗拼音移到第一位。

6. 安装oh-my-zsh
- 先安装zsh
sudo apt install zsh
- 把默认shell改为zsh
chsh -s /bin/zsh
或按照这样修改终端配置
- 安装oh-my-zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
7. 取消显示桌面图标
安装tweak-tool
sudo apt install gnome-tweak-tool
打开后，在桌面一栏，将show icons取消
8. 安装gcc、g++
sudo apt install gcc
sudo apt install g++
若有依赖问题，一般可使用sudo apt install -f解决。
Ps: -f 是--fix-broken的缩写，并非强制执行。
