arm64 ubuntu18.04桌面文件系统制作_ubuntu arm desktop

适用于RK3568，亲测有效

1、下载ARM64根文件系统 ubuntu-base-18.04.5-base-arm64.tar.gz

http://cdimage.ubuntu.com/ubuntu-base/releases/18.04/release/​​​​​​​

mkdir ubuntu_rootfs
tax xvf ubuntu-base-18.04.5-base-arm64.tar.gz -C ubuntu_rootfs

2、进入base系统

mount -t proc /proc ./ubuntu_rootfs/proc
mount -t sysfs /sys ./ubuntu_rootfs/sys
mount -o bind /dev ./ubuntu_rootfs/dev
mount -o bind /dev/pts ./ubuntu_rootfs/dev/pts
chroot ubuntu_rootfs
echo "nameserver 114.114.114.114" > /etc/resolv.conf

3、修改下载源
/etc/apt/source.list，修改内容如下

deb http://mirrors.huaweicloud.com/ubuntu-ports/ bionic main multiverse restricted universe
deb http://mirrors.huaweicloud.com/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb http://mirrors.huaweicloud.com/ubuntu-ports/ bionic-proposed main multiverse restricted universe
