制作Ubuntu根文件系统
制作Ubuntu根文件系统：
gunzip ubuntu-base-22.04.5-base-arm64.tar.gz
mkdir ubuntu
tar xvpf ubuntu-base-22.04.5-base-arm64.tar -C ubuntu
挂载目录、复制dns、执行chroot
cd /userdisk/ubuntu
cp /etc/resolv.conf ./etc/resolv.conf
mount --bind /dev ./dev
mount --bind /dev/pts ./dev/pts
mount --bind /proc ./proc
mount --bind /sys ./sys
mkdir rootdir
mount --bind / ./rootdir
cd /userdisk/ubuntu
chroot .
su root
先进入root用户执行apt update 否则会一直报错
su root
apt update
apt update报错解决
/dev/null权限
chmod 777 /dev/null
GPG error: http://ports.ubuntu.com
chmod 1777 /tmp
