我正在尝试关注准备就绪在 Ubuntu 14.04 上安装 Snapcraft 的说明（该文档对 14.04 和 16.04 有歧义，但1.x安装过程似乎完全相同）。
我按照步骤操作，没有出现错误，但是无法snapcraft安装。

我这里遗漏了什么吗？
尽管安装时snappy也snappy-remote出现错误：
$ snappy try
Unknown command `try'. Please specify one command of: booted, build, config, firstboot, hw-assign, hw-info, hw-unassign, info, install, internal-run-hooks, internal-unpack, list, login, purge, remove, rollback, search, set, update or versions
$ snappy-remote
the required flag `--url' was not specified
答案1
看来我们的 14.04 打包元数据中有一个错误。这个问题将会被修复，但是如果你遇到这种情况，只需确保安装了 snapcraft 即可：
sudo apt install snapcraft
只要snappy try和snappy-remote给出一些输出，就意味着它们已安装。我们将--help在未来版本中将它们替换为 ，因为它们在没有任何参数的情况下触发的错误可能会令人费解。
答案2
Snapcraft 也可以snap自行安装：
sudo snap install snapcraft
apt但我不知道这是否是一种更好的方法。
