Infos:
- Used Zammad version: 5.0
- Used Zammad installation type: (source, package, docker-compose, …) Package
- Operating system: Ubuntu 18.04
- Browser + version: Chrome - latest
Expected behavior:
Run sudo apt update and sudo apt upgrade commands to make sure Zammad is upgraded to latest version
Actual behavior:
When running sudo apt update, I get the following:
Err:7 https://dl.packager.io/srv/deb/zammad/zammad/stable/ubuntu 18.04 InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B6D583CCBD33EEB8
Reading package lists... Done
W: GPG error: https://dl.packager.io/srv/deb/zammad/zammad/stable/ubuntu 18.04 InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B6D583CCBD33EEB8
E: The repository 'https://dl.packager.io/srv/deb/zammad/zammad/stable/ubuntu 18.04 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.
Steps to reproduce the behavior:
Run: sudo apt update
I have already run:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B6D583CCBD33EEB8
but that didn’t fix anything, still getting the error.
Also made sure gpg is installed based on another post.
What am I missing?
