在使用vi编辑器时，插入状态下，上下左右键失效变成ABCD。
系统为Ubuntu22.04.（建议先检查第五条apt源的问题）
解决方法:
1.尝试修复破损依赖（大概率解决不了）
sudo apt --fix-broken install
2.如果是报版本错误，尝试降级
sudo apt remove vim-common
安装系统提示的版本
sudo apt install vim-common=xxx vim
3.清理包管理器缓存
清除所有包缓存
sudo apt clean
仅删除过期不可用的软件包
sudo apt autoclean
4.重新安装
sudo apt update
sudo apt install vim
5.换源（如果还是不行，可能是镜像源出问题了）
备份：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
换源（vi不正常，先使用nano）
sudo nano /etc/apt/sources.list
将原来的源注释或者删除，添加新的源
