无法添加 snappy-dev/tools ppa 存储库

我正在使用 Deepin Linux 15.4.1，当我尝试使用以下命令添加 snappy-dev/tools 存储库时，我想安装 snapcraft 包（为此，我需要“标题的存储库”）：

sudo add-apt-repository ppa:snappy-dev/tools

但我收到错误：

 Official PPA for the Snappy related tools.
  More info: https://launchpad.net/~snappy-dev/+archive/ubuntu/tools
 Press [ENTER] to continue or ctrl-c to cancel adding it

当我第二次尝试添加存储库时，我得到：

Snappy 相关工具的官方 PPA。更多信息：https://launchpad.net/~snappy-dev/+archive/ubuntu/tools 按 [ENTER] 继续或按 ctrl-c 取消添加

我在论坛上阅读了很多有关此内容的建议，但没有找到任何与我的错误相同的帖子。我尝试添加与 snap 相关的其他存储库，但遇到了与本文中所述相同的错误；我该如何解决这个问题？

这从评论中回答：

snap install --candidate --classic snapcraft
