For several days I’ve been trying to convert the latest version of RPI Image from 2019-06-20 and get the same result.
After starting the following command:
./docker-mender-convert from-raw-disk-image
–raw-disk-image $RAW\_DISK\_IMAGE
–mender-disk-image $MENDER\_DISK\_IMAGE
–device-type $DEVICE\_TYPE
–artifact-name $ARTIFACT\_NAME
–bootloader-toolchain arm-buildroot-linux-gnueabihf
–server-url “[https://hosted.mender.io](https://hosted.mender.io)”
–tenant-token $TENANT\_TOKEN
The following output of the console is received:
Running mender-convert from-raw-disk-image --raw-disk-image input/2019-06-20-raspbian-buster.img --mender-disk-image 2019-06-20-raspbian-buster.sdimg --device-type raspberrypi3 --artifact-name 2019-06-20-raspbian-buster --bootloader-toolchain arm-buildroot-linux-gnueabihf --server-url [https://hosted.mender.io](https://hosted.mender.io) --tenant-token
Then there is no change for 24 hours or more. Where is the problem?
How can I debug mender-convert?
How can I make detailed logs to understand what’s happening and how to fix it?
When I type “ps -eaf | grep mender”, the following processes are started:

A detailed log is written to `output/build.log`, I would inspect that. It definitely seems wrong that there is no change for 24 hours.
I believe the problem is that your `TENANT_TOKEN` variable is empty, or did you mask it when posting the log?

Currently is empty. Is TENANT\_TOKEN variable mandatory?
As I know, to have TENANT\_TOKEN, I have to pay membership here [hosted.mender.io](http://hosted.mender.io). Is it true?

> Currently is empty. Is TENANT\_TOKEN variable mandatory?
It is not mandatory, but you can not have empty values. So just remove `--tenant-token` if you are not provided that value. You can check `./mender-convert --help` for other available server options.

Yes, this requires you to have an account on [hosted.mender.io](http://hosted.mender.io)
