Host upgrade and repository migration

TIP

Are you tired of complex setup, configuration, backup and update tasks? Let us handle this stuff for you! 🚀

The easiest and often most cost-effective way to operate Zammad is our cloud service. Give it a try with a free trial instance!

This page covers the required steps for a host upgrade and to switch to Zammad's new package repositories. If you just want to update Zammad itself, please refer to Updating Zammad. To just switch to the new repositories without a host upgrade, skip the host upgrade steps.

Zammad packages are being built with a new toolchain and are hosted under another URL. The old toolchain is no longer in use, so the packages in the old repositories no longer receive updates. This means you need to add a new repository key and change your repository configuration.

The repository channel in the URL selects the release line: stable contains the current stable release, while release lines that are out of support have a channel of their own, for example stable-6.5.

WARNING

Always make sure to have a backup of your data before performing an upgrade.

WARNING

Zammad 6.5.5 is an emergency release that fixes a security issue. Zammad 6.5 is out of support and its packages are only available in the stable-6.5 channel. See Update an out-of-support release below for the steps.

The following operating systems are supported:

Distribution	Version
CentOS/RHEL	9, 10
Debian	12 & 13
OpenSUSE Leap / SLES	15 & 16
Ubuntu	22.04, 24.04 & 26.04

Stop Zammad

sudo systemctl stop zammad

Host upgrade steps

Disable updates for Zammad

sudo apt-mark hold zammad

Perform host upgrade

Perform the host upgrade according to the documentation of your operating system. Because this is an advanced task, we don't provide detailed steps here. After upgrading your operating system, proceed with the next steps.

Reboot host

In case you did not reboot your system after the upgrade, make sure to reboot your system now. Afterwards, check if everything is running as expected. In case Zammad starts automatically, stop it again before proceeding with the next steps.

Adjust package repository

Remove old repository

Remove the old repository configuration file or disable/delete the old repository in your package manager.

Ubuntu 22.04:

sudo rm /etc/apt/sources.list.d/zammad.sources

Ubuntu 24.04:

sudo rm /etc/apt/sources.list.d/zammad.list

Remove old repository key

Remove the old repository key from your system. Depending on your operating system and version, the location or method differs.

sudo rm /etc/apt/keyrings/pkgr-zammad.gpg

Add new repository

If the repository key is different for the old and new version your distribution or your distribution expects it in a different location, add the new one. Otherwise, you can add the new repository configuration directly.

Add repository key:

sudo curl -fsSL "https://go.packager.io/srv/deb/zammad/zammad/gpg-key.gpg" \
  -o /usr/share/keyrings/zammad.gpg && sudo chmod 644 /usr/share/keyrings/zammad.gpg

Add repository (Ubuntu 22.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable/installer/ubuntu/22.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Add repository (Ubuntu 24.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable/installer/ubuntu/24.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Add repository (Ubuntu 26.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable/installer/ubuntu/26.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Install Zammad

sudo apt update

sudo apt install zammad

Update Zammad

TIP

If there is a new Zammad version available and you want to update to it, check the release notes for any required additional steps.

Re-enable updates for Zammad and update Zammad to the latest version available for your operating system.

Update package index:

sudo apt update

Re-enable updates for Zammad:

sudo apt-mark unhold zammad

Update Zammad:

sudo apt upgrade zammad

Start Zammad

sudo systemctl start zammad

Update an out-of-support release

Zammad 6.5.5 is an emergency release that fixes a security issue. Zammad 6.5 has been out of support for some time and no longer receives security updates, so updating to the current stable release is the recommended action. Follow the steps below only if you cannot update to a supported release right now.

Zammad builds 6.5.5 packages for Ubuntu 20.04, 22.04 and 24.04, Debian 11 and 12, CentOS/RHEL 8 and 9, and OpenSUSE Leap/SLES 15.

Add the 6.5 repository

Remove the old repository and its key first, as described in Adjust package repository above. Otherwise your package manager keeps reading the old repository, which offers packages of a newer release line.

Add the new repository with the stable-6.5 channel:

Add repository key:

sudo curl -fsSL "https://go.packager.io/srv/deb/zammad/zammad/gpg-key.gpg" \
  -o /usr/share/keyrings/zammad.gpg && sudo chmod 644 /usr/share/keyrings/zammad.gpg

Add repository (Ubuntu 20.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable-6.5/installer/ubuntu/20.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Add repository (Ubuntu 22.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable-6.5/installer/ubuntu/22.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Add repository (Ubuntu 24.04):

sudo curl -fsSL "https://go.packager.io/srv/zammad/zammad/stable-6.5/installer/ubuntu/24.04.list" \
  -o /etc/apt/sources.list.d/zammad.list

Update Zammad to 6.5.5

Stop Zammad:

sudo systemctl stop zammad

Update package index:

sudo apt update

Re-enable updates for Zammad:

sudo apt-mark unhold zammad

Update Zammad:

sudo apt upgrade zammad

Start Zammad:

sudo systemctl start zammad
