sudo: /etc/sudo.conf is owned by uid 100000

在Pve安装了Ubuntu20.04的Lxc容器，进入后使用sudo时报错了。

sudo: /etc/sudo.conf is owned by uid 100000, should be 0
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

查看了一下 /etc/sudo.conf文件的权限发现是100000。

root@zngw:~# ll /etc/sudo.conf 
-rw-r--r-- 1 100000 100000 4343 Apr  8  2024 /etc/sudo.conf

这个修改一下sudo.conf文件权限就可以了。如果是root用户登录，直接修改

chmod root:root /etc/sudo.conf

如果不是root用户登录，先用su切换到root用户来操作

su -  # 然后输入 root 密码 
chown root:root /etc/sudo.conf
