如何在 14.04 上安装 Snapcraft？

Question

我正在尝试遵循在 Ubuntu 14.04 上安装 Snapcraft 的设置说明（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，没有错误，但是我无法snapcraft安装。

• 检查版本：

  $ lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 14.04.4 LTS
  Release:    14.04
  Codename:   trusty
  

• 添加存储库：

  $ sudo apt-add-repository ppa:snappy-dev/tools
  ...
  OK
  

• 运行更新：

  $ sudo apt update
  ... (altogether 57 lines, no error) ...

• 验证安装：

  $ which snappy
  /usr/bin/snappy
  $ which snappy-remote
  /usr/bin/snappy-remote
  $ which snapcraft
  $ snapcraft
  snapcraft: command not found
  $ find / -name snapcraft 2> /dev/null
  $
  

我在这里错过了什么吗？

此外snappy，snappy-remote虽然正在安装会出现错误：

$ 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

Answer 1

14.04 的打包元数据似乎存在错误。这将被修复，但如果你遇到这种情况，只需确保安装了 snapcraft：

sudo apt install snapcraft

只要 和snappy try给出snappy-remote一些输出，就意味着它们已安装。我们将在未来的版本中切换它们，--help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。
