使用教程提供的源再进行sudo apt install ... 可能会出现 Unmet dependencies 此类报错

可以安装 aptitude

sudo apt install aptitude
sudo aptitude install <package>

然后它会提示你，选 n 进行降级。再选 Y 确认

或者

将 /etc/apt/sources.list 下的源改为

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse

再输入

sudo apt-get update
sudo apt-get upgrade

对于 git，克隆 ssh 仓库

可能会遇到 ssh: connect to host github.com port 22: Connection refused 这样的报错

解决方案是在 ~/.ssh/config

如果没有则 touch ~/.ssh/config

vim ~/.ssh/config

在其中添加这几行：

Host github.com
  Hostname ssh.github.com
  Port 443

然后再进行 git clone

当我们运行 make menuconfig

出现以下报错

我们需要安装这些缺少项

sudo apt install bison

再尝试输入 make

同理，安装

sudo apt install flex

即可正常编译
