运行apt更新时Skype更新错误

Question

当我运行sudo apt-get update更新系统时，控制台底部出现此错误：

W: GPG error: https://repo.skype.com/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3
W: The repository 'https://repo.skype.com/deb stable InRelease' is not signed.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Skype 出了什么问题？是否有任何风险，因为错误表明 Skype 存储库使用危险？

我使用 Ubuntu 16.04。

根据https://repo.skype.com/，运行：

curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add - 

在一个终端。
