TX2 刷 Jetpack4.2 后的换源问题

NVIDIA TX2 刷 Jetpack4.2后 的ARM换源问题

---

Keypoint:

1. Jetpack4.2刷机过后的系统版本为ubuntu18.04
2. TX2 本身 为ARM64架构的 CPU
3. Ubuntu18.04的apt软件配置文件是/etc/apt/sources.list

x86 架构下的清华镜像源：
ubuntu18.04软件清华源

1. 备份：sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
2. 修改更新源：sudo vim /etc/apt/sources.list
3. 上述连接中为x86架构的软件源，arm64的软件源修改如下：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main restricted universe multiverse

• 常规操作：sudo apt-get update
