本文介绍了如何在Ubuntu系统中通过PPA源安装GCC 7版本，包括添加PPA、更新源、修复依赖错误，并切换gcc和g++版本的过程，适合初学者参考。

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-7
sudo apt-get install g++-7

出现以下错误：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gcc-7 : Depends: cpp-7 (= 7.5.0-3ubuntu1~16.04) but it is not going to be installed
         Depends: libgcc-7-dev (= 7.5.0-3ubuntu1~16.04) but it is not going to be installed
 wine-wechat : Depends: wine-stable but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

sudo apt --fix-broken install

然后继续：

sudo apt-get install gcc-7

切换gcc版本
