Disk images

These disk images (*.img or *.sdimg) are based on images provided by board manufacturers and are ready to install the Mender client. They are used to provision the device storage for devices without Mender running already.

Mender provides images based on the following distributions:

Note that we do not offer commercial support for these images. They are based on images supported by board manufacturers, like the Raspberry Pi Foundation, and provide the same software and configuration options as the original images. Please use the support resources available from the board manufacturer, or contact us if you have any questions on the Mender integration.

Board OS Disk image Storage size
Raspberry Pi 3 Model B and B+ Raspberry Pi OS Bullseye Lite 2022-01-28 raspios-bullseye-armhf-lite-raspberrypi3-mender.img.xz 8 GB
Raspberry Pi 4 Model B Raspberry Pi OS Bullseye Lite 2022-01-28 raspios-bullseye-armhf-lite-raspberrypi4-mender.img.xz 8 GB

You can find images for other devices in our Mender Hub community forum, see Debian Family or Yocto Project integration posts.

mender-artifact

The mender-artifact utility is used to work with Mender Artifacts, which are files with the .mender suffix and contain software to be deployed. See Artifact creation for more information on how to use this utility.

Follow the correct link according to your host platform to download mender-artifact as a standalone utility:

Platform Download link
Linux mender-artifact 3.8.1 mender-artifact master (Pre-release)
Mac OS X mender-artifact 3.8.1 mender-artifact master (Pre-release)

Remember to add execute permission and ensure that the mender-artifact utility is in a directory that is specified in your PATH environment variable. Most systems automatically have /usr/local/bin in your PATH so the following should allow proper execution and location of this binary.

sudo chmod +x mender-artifact
sudo cp mender-artifact /usr/local/bin/

Please refer to your host Operating System documentation for more details.

If you are using Mac OS X, note that using mender-artifact with disk image files (e.g.: *.sdimg, *.img, or others holding the storage partitions) has limited functionality. Commands like mender-artifact cat or mender-artifact cp will not work due to lack of support for certain utilities on the Mac platform.

Mender client

The Mender client runs on the device, checks for and installs software updates packaged as Mender Artifacts. See Client installation for more information about how to configure and use the Mender client.

Installation methods

You can install the Mender client in different ways depending on your preference.

Express installation

Mender provides a convenience script available at get.mender.io that non-interactively installs the Mender client using the package manager. Users installing the Mender client this way, should be aware that:

  • The script requires root privileges to run. Therefore, carefully examine the script before executing it.
  • The script will install several dependencies with the package manager without asking for confirmation.
  • The Mender GPG public key and APT repository will be added to your trusted APT keychain and sources list respectively without asking for confirmation.
  • The latest released Mender components will be installed.

Always examine scripts downloaded over the Internet before running them locally.

curl -fLsS https://get.mender.io -o get-mender.sh
# INSPECT get-mender.sh BEFORE PROCEEDING
sudo bash get-mender.sh

By default, the script installs the remote terminal extension plugin in addition to the client. If you do not want this feature you can provide additional arguments to the script specifying which packages you want to install. For example, the following will only install the Mender client:

curl -fLsS https://get.mender.io -o get-mender.sh
# INSPECT get-mender.sh BEFORE PROCEEDING
sudo bash get-mender.sh mender-client

Mender offers an experimental version of the package repository. To use the latest experimental version of Mender, run the script with an additional flag -c experimental. Do not use the experimental repository for production devices as these releases are not fully tested.

Upgrading Mender after the express installation

After installing the Mender client with get.mender.io, the mender-client package is maintained by the package manager. To upgrade the Mender client, simply run

sudo apt-get update
sudo apt-get upgrade

To prevent the Mender client from upgrading when upgrading the rest of the system, mark it to be held with sudo apt-mark hold mender-client.

Updating mender this way doesn't provide a rollback mechanism in case of issues. For production devices always update mender as part of the full system update with A/B partitions.

Install using the APT repository

Before installing the Mender client, you need to set up the Mender APT repository. Afterwards, you can install and update the Mender client using the apt command line interface.

Set up the APT repository

As of Mender 3.2.1 we deprecated the previous stable repository and stopped updating it. As of Mender 3.3 we removed it. Please use https://downloads.mender.io/repos/debian debian/buster/stable main and not "https://downloads.mender.io/repos/debian stable main". Please make sure you have the currently supported version of your choice in place and please see below for all the possible options.

With this method, you will always install the latest released Mender components. If you need to install a specific version, or you want to stick to a specific minor release (e.g., to the latest LTS version), you can manually download the Debian packages from the APT repository pool.

  1. Update the apt package index and install required dependencies.
   sudo apt-get update
   sudo apt-get install --assume-yes \
        apt-transport-https \
        ca-certificates \
        curl \
        gnupg-agent \
        software-properties-common

  1. Add the official Mender GPG key to your trusted apt keychain:

    curl -fsSL https://downloads.mender.io/repos/debian/gpg | sudo tee /etc/apt/trusted.gpg.d/mender.asc

    Inspect the GPG key fingerprint and verify that it matches E6C8 5734 5575 F921 8396 5662 2407 2B80 A1B2 9B00.

   gpg --show-keys --with-fingerprint /etc/apt/trusted.gpg.d/mender.asc
   pub   rsa3072 2020-11-13 [SC] [expires: 2024-10-23]
         E6C8 5734 5575 F921 8396  5662 2407 2B80 A1B2 9B00
   uid                      Mender Team <mender@northern.tech>
   sub   rsa3072 2020-11-13 [E] [expires: 2024-10-23]

  1. Add the Mender repository to your sources list by selecting the architecture matching your device.

    First in order to make sure that there are no mender sources in '/etc/apt/sources.list' lingering from a previous install, run

      sed -i.bak -e "\,https://downloads.mender.io/repos/debian,d" /etc/apt/sources.list

Then add the sources according to your Linux distribution

For Raspberry OS, use Debian distributions. To know which version is your device running, do (. /etc/os-release && echo $VERSION_CODENAME)

    echo "deb [arch=$(dpkg --print-architecture)] https://downloads.mender.io/repos/debian debian/bullseye/stable main" \
    | sudo tee /etc/apt/sources.list.d/mender.list > /dev/null

If you want the bleeding edge version of mender, you can use our experimental repository by replacing stable with experimental in the above command. Do not use the experimental repository in production as these releases are not fully tested.

  1. Update the package index and install the Mender client:
   sudo apt-get update
   sudo apt-get install mender-client

To prevent the Mender client from upgrading when upgrading the rest of the system, mark it to be held with sudo apt-mark hold mender-client.
