I tried to use removing the key using
apt-key list and then removing using the id, it successfully removed the key but when i use
apt update i get this output:
W: GPG error: http://download.opensuse.org/repositories/home:/Horst3180/Debian_8.0 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A7D1D38BEB6D886 E: The repository 'http://download.opensuse.org/repositories/home:/Horst3180/Debian_8.0 Release' 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.
I just want to be able to run
apt update normally like when a fresh OS install was made
