如何解决无法在BeagleBoneBlackrevC上安装python3
BeagleBoneBlack revC装有Python2。但是我们需要运行Python3。
但是，尝试使用apt-get安装python3失败。似乎尝试安装下载站点上不存在的3.2版（请参见http://ftp.us.debian.org/debian/pool/main/p/python3-defaults/）

E: Unable to fetch some archives,maybe run apt-get update or try with --fix-missing?
尝试指定版本时，它也会失败：
root@beaglebone:~# sudo apt-get install python3=3.4

有什么建议吗？
谢谢！
解决方法
我建议获取它们提供的图像的更新版本。我知道python3已预先安装在映像的Buster版本中。

,是的。 wheezy很老了，没有时间在浪费时间。将debian映像升级到最新版本可以轻松解决。谢谢！
