Recently (24 Jul 2017) our packaging service provider (packager.io: http://www.packager.io/) improved its package distribution which makes it necessary that you update your Zammad repo file (e. g. /etc/apt/sources.list.d/zammad.list or /etc/yum.repos.d/zammad.repo) on your operating system.
If you're using an old repo file, you will not be able to update Zammad.
For more background information see: https://blog.packager.io/posts/24-change-of-repository-urls
Please use the following commands to update your Zammad repo file:
sudo yum -y install epel-release wget sudo wget -O /etc/yum.repos.d/zammad.repo https://dl.packager.io/srv/zammad/zammad/stable/installer/el/7.repo sudo yum install zammad
sudo apt-get install wget wget -qO- https://dl.packager.io/srv/zammad/zammad/key | sudo apt-key add - sudo wget -O /etc/apt/sources.list.d/zammad.list https://dl.packager.io/srv/zammad/zammad/stable/installer/debian/8.repo sudo apt-get update sudo apt-get install zammad
sudo apt-get install wget wget -qO- https://dl.packager.io/srv/zammad/zammad/key | sudo apt-key add - sudo wget -O /etc/apt/sources.list.d/zammad.list https://dl.packager.io/srv/zammad/zammad/stable/installer/debian/9.repo sudo apt-get update sudo apt-get install zammad
sudo apt-get install wget wget -qO- https://dl.packager.io/srv/zammad/zammad/key | sudo apt-key add - sudo wget -O /etc/apt/sources.list.d/zammad.list https://dl.packager.io/srv/zammad/zammad/stable/installer/ubuntu/16.04.repo sudo apt-get update sudo apt-get install zammad
sudo zypper install wget sudo wget -O /etc/zypp/repos.d/zammad.repo https://dl.packager.io/srv/zammad/zammad/stable/installer/sles/12.repo sudo zypper install zammad
If you're using an old repo file, you will get error messages like these:
