Moosh installation problem (public key)

[wolfstettler]

Good morning

we are having an issue with installing Moosh on a Ubuntu server. We get the following error message: " W: GPG error: http://ppa.launchpad.net/zabuch/ppa/ubuntu trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY CA1F0167ECFEA950 E: The repository 'http://ppa.launchpad.net/zabuch/ppa/ubuntu trusty 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.Publ " Can the public key used to sign the repository be obtained somewhere? We did not find it.

Many thanks Wolf
