新手尝试在 16.04 上使用 lxc 容器。它正在运行，但我无法在其中发出命令或进入它（尝试过“uptime”，但任何命令都一样）。而且它似乎没有我“认为”（什么都不知道！）它应该有的 IP 地址。任何帮助都非常感谢...

LXC和之间存在重要区别LXD。
LXC是创建和管理容器的原始、较旧（但仍受支持）方式。 的命令行工具LXC是类似lxc-create和 的命令lxc-info。也就是说，它们只是以 开头的命令lxc-。
LXD是创建和管理容器的新方法，它比 更简单、更用户友好LXC。使用LXD，您可以使用lxc命令执行所有管理任务。例如，lxc launch ubuntu:18.04 mycontainer将使用 Ubuntu 18.04 创建一个名为 mycontainer 的新容器。lxc info mycontainer将显示有关容器的信息。此外，LXD已预安装在 Ubuntu 上。LXC不是。
很多人在LXD使用该lxc命令时感到困惑。

回到你的问题。你使用了用 创建的容器的LXD命令。lxcLXC
