Issue with Including `mender` in an Image While Using `mender-full`

Hi all,

I’m running into a problem while building a Yocto image with Mender. My goal is to include the mender-full integration for automated partition and update handling, and also have the mender CLI available on the device so I can run commands like mender --version.

Here’s the issue:

  • When I include the following line in my local.conf:
INHERIT += "mender-full"
  • And try to add mender explicitly to my image:
IMAGE_INSTALL:append = " mender"

The build fails with the following error:

ERROR: core-image-minimal-1.0-r0 do_rootfs: Unable to install packages. Command '/workdir/build/tmp/work/qemuarm64-poky-linux/core-image-minimal/1.0/recipe-sysroot-native/usr/bin/opkg ... install ca-certificates hellocustom helloworld htop mender mender-artifact-info mender-keys packagegroup-core-boot packagegroup-core-ssh-openssh rollback-test run-postinsts vim' returned 255:

ERROR: Logfile of failure stored in: /workdir/build/tmp/work/qemuarm64-poky-linux/core-image-minimal/1.0/temp/log.do_rootfs.370110
ERROR: Task (/workdir/poky/meta/recipes-core/images/core-image-minimal.bb:do_rootfs) failed with exit code '1'
  • If I remove the INHERIT += "mender-full" line, the build succeeds and mender can be installed. But then I lose the full Mender integration features (mender-full) that are required for automated partitioning and update handling.

On the device, when mender-full is included without explicitly adding mender, the CLI and service are missing:

root@qemuarm64:/# which mender
root@qemuarm64:/# mender --version
-sh: mender: not found

root@qemuarm64:/# systemctl status mender
Unit mender.service could not be found.

root@qemuarm64:/# systemctl start mender
Failed to start mender.service: Unit mender.service not found.

root@qemuarm64:/# systemctl enable mender
Failed to enable unit: Unit file mender.service does not exist.

root@qemuarm64:/# journalctl -u mender
-- No entries --

My Goal

  • Keep mender-full in the image to enable automated partitioning and rollback features.
  • Be able to use mender commands on the device (mender --version, mender daemon, etc.).

Has anyone encountered this issue or can suggest a proper way to include both mender-full and the mender CLI in a Yocto image without causing the package installation failure?

Thanks in advance for any help!

Hi @Stan,

The mender-full integration does already install the Mender Client.
During the version upgrade 3.x → 4.x, the mender binary got split into mender-update and mender-auth. Can you check if those are present?
Explicitly adding something to IMAGE_INSTALL should absolutely not be necessary. You can find more information about the breaking changes at Upgrading | Mender documentation

Greetz,
