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

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/shsudo 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。
