Ubuntu Desktop Mender Conversion not booting up

Hi!

My setup is:

  • Raspberry Pi 4 as the client
  • M1 Mac for building the images
  • Using linux/amd64 based mender-convert docker image

I have tried converting a Raspberry Pi OS golden image without any problems before but when I tried converting my 64-bit Ubuntu Desktop golden image it was taking too long to convert the OS and the outputted image didn’t boot on my RPi 4. How I ran it:

MENDER_ARTIFACT_NAME=release-1 ./docker-mender-convert --disk-image input/golden-image-1-raspberrypi4-ubuntu-mender.img --config configs/raspberrypi4_ubuntu_config --config configs/custom_config --overlay input/rootfs_overlay_demo

The custom_config file only contains: MENDER_STORAGE_TOTAL_SIZE_MB=25000.
The overlay file only contains secrets Mender uses to connect to server.

Any help would be appreciated. :slight_smile:

Hi @Neil1,

Currently there is no 64bit support for the Raspberry Pis in mender-convert, so probably that is the reason.

Greetz,

Thanks, Josef! I should’ve checked the github page :grimacing:. My bad
