Download instructions

The easiest way to get your hands on the software is to add the Copernica repository to the source list of your package manager. You can then use "apt" package manager to install MailerQ and to get updates. If you do not want to use your package manager, you can download MailerQ manually. Check out our downloads page for a list of available files that can be manually installed.

Installing MailerQ on Debian/Ubuntu based systems

MailerQ comes in two separate packages which are available on one of our repositories. Each supported operating system has its own repository.

Configuring the APT repository

First add the MailerQ repository to your system. This is the repository from which all MailerQ software can be downloaded. For Ubuntu 22.04, Debian 11 and newer Debian based distros you can use the following instructions:

# download and install the gpg key
sudo gpg --homedir /tmp --no-default-keyring --keyring /usr/share/keyrings/mailerq-packages.gpg --keyserver keyserver.ubuntu.com --recv-keys 90DE523265E3563E

# find out the distro name
MY_DISTRO=`lsb_release -c -s`

# add the repo
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/mailerq-packages.gpg] https://packages.mailerq.com/debian $MY_DISTRO main" | sudo tee /etc/apt/sources.list.d/mailerq-packages.list

Older versions of Debian and Ubuntu still support apt-key, which is less secure, but also simpler:

# download and install the gpg key
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 90DE523265E3563E

# add the repo
sudo apt-add-repository https://packages.mailerq.com/debian

Install the MailerQ frontend and backend

The MailerQ frontend and backend are distributed in separate packages, so that bugfixes to the frontend can be brought out without forcing a restart of MailerQ. Both packages can be installed independently:

# make sure apt definitions are up-to-date
sudo apt update

# install the latest MailerQ-server
sudo apt install mailerq-server

# install the latest mailerq-frontend
sudo apt install mailerq-frontend

Updating MailerQ

New versions are automatically installed every time that you run "apt ugrade":

# make sure the local apt cache is up-to-date
sudo apt update

# get upgrades for all installed packages
sudo apt upgrade

Dynamically linked versions

All repositories mentioned above contain MailerQ versions that are statically linked, which means that there are not many dependencies. However, due to licensing conditions, we are required to supply dynamically linked versions of MailerQ too. If you prefer using a dynamically linked version, you can send an email to info@mailerq.com to request the specific dynamically linked version you need.
