此次拿到的不知名板子已经有大佬移植了ubuntu16.04系统dpkg --print-architecture时显示的是arm64。如果直接照搬桌面系统的软件源进行更新会出现如下的not found 问题。/main/binary-arm64/Packages 404 Not Found这时尝试清华源、阿里源、东北大学源等都是一样的。网上搜索的方法提到的主要是针对Nvidia TX1的就是在源中的deb后增加:[archamd64,i386]举个例子deb [archamd64,i386] http://mirror.neu.edu.cn/ubuntu/ xenial main restricted更具体的说明这里不展开了详见参考链接1然而这样治标不治本这里替换的源应当是树莓派等开发板的源于是我查看了下树莓派的源和tx1的源拷贝到了板子里更新下就OK了。# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to# newer versions of the distribution.deb http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted universe multiversedeb-src http://ports.ubuntu.com/ubuntu-ports/ xenial main restricted universe multiverse## Major bug fix updates produced after the final release of the## distribution.deb http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted universe multiversedeb-src http://ports.ubuntu.com/ubuntu-ports/ xenial-updates main restricted universe multiverse## Uncomment the following two lines to add software from the universe## repository.## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu## team.
