Skype的回购/密钥

我有17.04,今天我安装了Skype for Linux,但是当我执行sudo apt update我得到以下内容:

 W: Errore GPG: https://repo.skype.com/deb stable InRelease: Le seguenti firme non sono state verificate perché la chiave pubblica non è disponibile: NO_PUBKEY 1F3045A5DF7587C3 E: The repository 'https://repo.skype.com/deb stable InRelease' is not signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. 

(第一行的翻译: GPG错误由于公钥不可用,因此未validation以下签名

我怎么解决?

问题是在使用deb安装程序安装skype之后,它会将skype的存储库添加到您的sources文件中,在向您的源添加存储库之后,您也应该添加其公钥,但是Skype似乎没有将其公钥添加到你的系统所以你应该手动添加它:

如此处所述:

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

如果你没有curl

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