Erro de atualização do Skype ao executar o apt update [duplicate]

Question

Quando executo o sudo apt-get update para atualizar o sistema, recebo esse erro na parte inferior do console:

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.

O que está errado com o Skype? Existe algum risco desde que o erro diz que o repo Skype é perigoso de usar?

Eu uso o Ubuntu 16.04.
