sudo chmod 777 -R /usr
Problem
-
解决普通用户sudo时出现/usr/bin/sudo must be owned by uid 0 and have the setuid bit set
-
If you forget root password: su Authentication failure解决方法
- WSL2 的 /etc/sudoers 文件改错后:/etc/sudoers: syntax error near line 30
- sudo: error in /etc/sudo.conf, line 0 while loading plugin ‘sudoers_policy’
