Install on Ubuntu via DEB


We currently support Ubuntu 16.04 LTS and 18.04 LTS.


Be sure to use an UTF-8 locale or PostgreSQL will not install.

Setup Elasticsearch

Elasticsearch is a dependency of Zammad and needs to be provided before installing Zammad. Please take a look at the following page: Set up Elasticsearch .

Check locale


If there is nothing with UTF-8 in the name shown like “LANG=en_US.UTF-8” you have to set a new locale.

Set locale

apt-get install apt-transport-https locales sudo wget
locale-gen en_US.UTF-8
echo "LANG=en_US.UTF-8" > /etc/default/locale

Add Zammad DEB Repo

Ubuntu 16.04

wget -qO- | sudo apt-key add -
sudo wget -O /etc/apt/sources.list.d/zammad.list \

Ubuntu 18.04

wget -qO- | sudo apt-key add -
sudo wget -O /etc/apt/sources.list.d/zammad.list \

Install on Ubuntu (16.04 and 18.04)

sudo apt-get update
sudo apt-get install zammad

Note: You might need to apt-get install wget apt-transport-https for the above instructions to work.

Go to http://localhost and you’ll see:

  • “Welcome to Zammad!”, there you need to create your admin user and invite other agents.

Change your webserver configuration (non localhost connections):

Add your fully qualified domain name or public IP to server name directive in your web server configuration and restart your web server. The installer will give you a hint where Zammad’s web server config file is located.



Please do not rename the webserver config file for nginx or apache. The update process will re create it, if it does not exist!


server {
    listen 80;

    # replace 'localhost' with your fqdn if you want to use zammad from remote
    server_name localhost;

You can manage the Zammad services manually:


sudo systemctl status zammad
sudo systemctl stop zammad
sudo systemctl start zammad
sudo systemctl restart zammad

sudo systemctl status zammad-web
sudo systemctl stop zammad-web
sudo systemctl start zammad-web

sudo systemctl stop zammad-worker
sudo systemctl start zammad-worker
sudo systemctl restart zammad-worker
