更换为西电ubuntu更新源

 vim /etc/apt/sources.list                           //打开更新目录

Telegram 安装

sudo add-apt-repository ppa:atareao/telegram
sudo apt update
sudo apt-get install telegram-desktop
sudo apt remove telegram               //此句卸载时候使用

Chrome 安装

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -                                    //下载并安装
sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'   //将官方源加入源列表
sudo apt-get update                                         //更新
sudo apt-get install google-chrome-stable                  //安装稳定版Chrome
sudo apt-get install google-chrome-beta                    //安装beta版Chrome
sudo apt-get install google-chrome-unstable                //安装不稳定版Chrome

SS 安装

sudo add-apt-repository ppa:hzwhuang/ss-qt5
ppa:hzwhuang/ss-qt5                                                // 并没有18.10的源，所以会报错：
E: 仓库 “http://ppa.launchpad.net/hzwhuang/ss-qt5/ubuntu bionic Release”
cd /etc/apt/sources.list.d/                                         //修改下面的hzwhuang-ubuntu-ss-qt5-bionic.list  去官网看看适配了那个
sudo vim hzwhuang-ubuntu-ss-qt5-bionic.list

修改为

deb http://ppa.launchpad.net/hzwhuang/ss-qt5/ubuntu Artful main

然后再执行：

sudo apt-get update
sudo apt-get install shadowsocks-qt5

Java安装

apt-cache search openjdk             //寻找合适版本
sudo apt-get install                 //安装自己想要的版本
java -version                        //检查是否配置成功
echo $java_home
which javac                          //寻找javac的路径，然后通过file 一步一步寻找
sudo echo export JAVA_HOME=”/usr/lib/jvm/java-11-openjdk-amd64/bin”>>~/.bashrc     //添加系统环境变量
source ~/.bashrc
gedit ~/.bashrc                      //测试是否配置成功
