ubuntu22.04 默认执行visudo时候会使用nano打开/etc/sudoers文件，编辑不方便
修改为vim，执行sudo update-alternatives --config editor命令，选择vim即可
➜ ~ sudo update-alternatives --config editor
There are 6 choices for the alternative editor (providing /usr/bin/editor).
Selection Path Priority Status
------------------------------------------------------------
* 0 /bin/nano 40 auto mode
1 /bin/ed -100 manual mode
2 /bin/nano 40 manual mode
3 /usr/bin/code 0 manual mode
4 /usr/bin/code-insiders 0 manual mode
5 /usr/bin/vim.basic 30 manual mode
6 /usr/bin/vim.tiny 15 manual mode
Press <enter> to keep the current choice[*], or type selection number: 5
update-alternatives: using /usr/bin/vim.basic to provide /usr/bin/editor (editor) in manual mode
➜ ~ sudo visudo
visudo: /etc/sudoers.tmp unchanged
