Ubuntu – Repo / key of Skype


I have 17.04 and today I installed Skype for Linux, but when I execute sudo apt update I get the following:

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.

(Translation of the first line: GPG error The following signatures were not verified since public key is not available)

How can I solve?

  • The problem is that after installing skype using its deb installer, it will add skype's repositories into your sources file, after adding a repository to your sources, you should add its public key too, however it seems that Skype did not add its public key to your system so you should add it manually:

    As here states:

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

    If you don't have curl:

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