I'm running linux debian 9.4.0 64-bit on my machine. Since I installed atom text editor, I receive an ERROR while running ap-get update. The error reads the following:
W: GPG-Fehler: https://packagecloud.io/AtomEditor/atom/any any InRelease: Die folgenden Signaturen konnten nicht überprüft werden, weil ihr öffentlicher Schlüssel nicht verfügbar ist: NO_PUBKEY 4C6E74D6C0A35108 W: The repository 'https://packagecloud.io/AtomEditor/atom/any any 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.
The first line says that the signature of my PGP key could not be verified, since a PUBKEY is unavailable.
The same error message continously shows, even though I purged atom from my system.
Can someone lend me a hand with making my system being updating properly again and how to install atom without causing future problems?
Thanks in advance!
