您可能知道 Chrome OS 正在运行 Linux 容器 (Crostini)，对于我的大学课程，我需要安装 Naviserver，它安装在
/usr/local/ns$
我的问题是我需要获得权限才能编辑位于此目录中的文件。所以我认为给我或多或少整个 usr 文件夹的以下权限是个好主意
/usr$ ls -l
drwxr-xr-x 755 /bin
drwxr-xr-x 755 /boot
drwxr-xr-x 755 /dev
drwxr-xr-x 755 /etc
drwxr-xr-x 755 /home
drwxr-xr-x 755 /lib
drwxr-xr-x 755 /lib32
drwxr-xr-x 755 /lib64
drwxr-xr-x 755 /media
drwxr-xr-x 755 /mnt
drwxr-xr-x 755 /opt
dr-xr-xr-x 555 /proc
drwx------ 700 /root
drwxr-xr-x 755 /run
drwxr-xr-x 755 /sbin
drwxr-xr-x 755 /srv
dr-xr-xr-x 555 /sys
drwxrwxrwt 1777 /tmp
drwxrwxrwx 777 /usr
drwxr-xr-x 755 /var
drwxrwxrwx 1 root root 16704 Dec 2 20:16 bin
drwxrwxrwx 1 root root 0 Nov 22 2020 games
drwxrwxrwx 1 root root 2956 Nov 17 18:21 include
drwxrwxrwx 1 root root 1298 Dec 2 18:08 lib
drwxrwxrwx 1 root root 102 May 12 2021 lib32
drwxrwxrwx 1 root root 6 Dec 30 2020 lib64
drwxrwxrwx 1 root root 416 Dec 2 18:07 libexec
drwxrwxrwx 1 root root 76 Nov 17 18:28 local
drwxrwxrwx 1 root root 4716 Dec 2 18:08 sbin
drwxrwxrwx 1 root root 2468 Dec 2 18:08 share
drwxrwxrwx 1 root root 0 Nov 22 2020 src
这当然弄乱了 sudo 文件夹。
当我想使用 sudo 命令时，这会导致以下问题
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
有没有办法重置权限以解决这个问题？
