Remote terminal not working

Hi,
Currently using Yocto and Mender with kirkstone branch.
I’ve installed mender-connect successfully, however, mender-client doesn’t have DBus enabled by default. DBus API is not available either on the /usr/share/dbus-1/ folder. Authentication and UpdateManager confs are not available on my rootfs.

I’ve tried to enable manually on the mender.conf and included the confs myself. The mender-client fails to start with the following message:
“DBus API support not available, but DBus is enabled: no D-Bus interface available”

Not sure how to enable dbus on the mender-client recipe.
What am I missing?

Best regards,
Nuno

Hi @nrmmota,

Thanks for getting in touch. Thats strange because given the meta-mender-core and possibly meta-mender-demo layers in the build it should work out of the box. Which board are you using, respectively how does your local.conf look like?

Greetz,
Josef

Hi,
Thank you for your feedback.
I’ve picked up some things from demo, but I’m not including it.

I’ve managed to understand what was missing.

Adding mender-client to the IMAGE_INSTALL doesn’t trigger the dbus part.
The dbus part is triggered when mender-client-install is added to the MENDER_FEATURES_ENABLE:append

The recipe source is here.
_MENDER_PACKAGECONFIG_DEFAULT = “${@mender_feature_is_enabled(“mender-client-install”, “dbus modules inventory-network-scripts”, “”, d)}”

Hope this helps others that eventually stumble upon this issue.
