本文主要讲述,基于 Jetson Xavier NX 开发者套件apt更换国内源。
What is Jetson Xavier NX :
- NVIDIA® Jetson Xavier™ NX 是体型超小的AI超级计算机,适用于嵌入式系统和边缘系统。
- 高达 21 TOPS 加速计算能力,可以并行运行现代神经网络并处理来自多个高分辨率传感器的数据。
- Jetson Xavier NX 是生产就绪型产品,可支持所有热门 AI 框架。
- 更换国内源比较简单,但是有的同学可能没有注意一些细节,即PC虚拟机和ARM核ubuntu系统更换源的差异,导致提示 E: Failed to fetch http://…,例如下所示:
E: Failed to fetch http://mirrors.aliyun.com/ubuntu/dists/bionic/main/binary-arm64/Packages 404 Not Found [IP: 120.223.240.248 80]

需要搞清楚的是:
- Jetson Xavier NX 默认系统是 Ubuntu18.04LTS,对应源关键字:“bionic”
- Jetson Xavier NX CPU是arm64的架构,镜像路径:xxx/ubuntu-ports/
因此,Jetson Xavier NX 更换源的步骤为:
(1) root权限,重新编辑source.list文件
sudo vim /etc/apt/sources.list
(2)更换内容为(用的是清华源,也可以搜索其他的源):
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-backports main restricted universe multiverse
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main universe restricted
deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main universe restricted
(3)更新源
sudo apt-get update
以上就完成了 Jetson Xavier NX 的apt源更新,下载速度会大幅提升.
