jetson nano官方的定制Ubuntu18.04 arm64系统，软件源为国外服务器，网速会很慢，需要换国内的ARM源。备份source.list文件sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak为防止误操作后无法恢复，先备份原文件sources.list更换源sudo vim /etc/apt/sources.list打开sources.list，将原来的内容使用”#”符号全部注释掉，然后在文件结尾出添加中国科学技术大学或清华的源 (我用的是中科大的)清华源deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-updates main restricted universe multiverse deb-src http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial-updates main restricted universe multiverse deb http://mirror
