测试环境：

Software part of jetson-stats 4.1.5 - (c) 2023, Raffaello Bonghi
Model: NVIDIA Jetson Xavier NX Developer Kit - Jetpack 5.0.2 GA [L4T 35.1.0]
NV Power Mode: MODE_20W_6CORE - Type: 8
jtop:
 - Version: 4.1.5
 - Service: Active
Libraries:
 - CUDA: 11.4.239
 - cuDNN: 8.4.1.50
 - TensorRT: 8.4.1.5
 - VPI: 2.1.6
 - Vulkan: 1.3.203
 - OpenCV: 4.5.4 - with CUDA: NO
 

jetson更换成清华源，也可以更换成阿里源/中科大等常用源，注意jepack5.02对于的是ubuntu20.04版本所以是focal而不是bionic（对应ubuntu18.04）。其中为了安装旧的libpng12需要加入xenial （ubuntu16.04）的源

备份文件：

sudo cp /etc/apt/source.list /etc/apt/source.list.bak

加入清华源：

sudo vi /etc/apt/source.list

   deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-updates main restricted universe multiverse
   deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-updates main restricted universe multiverse

   deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal-backports main restricted universe multiverse

   deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ focal main universe restricted
   deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe

保存后：
