当我尝试安装landscape-server-quickstart 或landscape-server时发生的情况如下：
joseph@slave-server:~$ sudo apt-get install landscape-server-quickstart
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package landscape-server-quickstart is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'landscape-server-quickstart' has no installation candidate
我遇到了“landscape-server”的相同错误。
到目前为止，我已经在两台 Ubuntu 15.10 物理机和一台 DigitalOcean 15.10 VPS 上尝试过此操作，但均未成功。有什么线索吗？
答案1
Landscape 仅针对 Ubuntu LTS 版本发布。目前最新的 LTS 是 Trusty (Ubuntu 14.04)，但几周后我们将推出新的 LTS - Xenial (Ubuntu 16.04)。
请尝试使用安装了 Landscape 16.03 版本的 Ubuntu Trusty 14.04 机器（您链接到的页面已更新以反映该新版本）。
