我在 PandaBoard 上运行了 Ubuntu Core，如下所示本指南Ubuntu Core 有 apt-get，所以我可以安装新软件包，但我想安装的一切都失败了。我使用过：
apt-get updateapt-get update --fix-missingapt-get install xxxxapt-get upgrade
但总是出现错误。如果我断开互联网连接，我就会得到完全相同的错误，所以我认为我没有通过以太网电缆上网。我已经安装了 Ubuntu Server，我可以正确安装所有内容，但 Ubuntu 服务器是 1.6Gb，而 Ubuntu Core 是 20Mb。Ubuntu Core 应该可以访问互联网，但我甚至无法测试它，因为我没有“ping”。
例如，这是我尝试安装时得到的结果apt-get install aptitude：
root@localhost:/home/andres# apt-get install aptitude

发生这种情况可能是因为图像不知道任何名称服务器。
您可以通过添加名称服务器来解决此问题，例如Google DNS
回显“名称服务器 8.8.8.8”> /etc/resolv.conf
如果您的内核还没有执行 DHCP 自动配置，您可能还需要让它处理该功能。
