Hi,
Please see the steps which I have done below:
- From PC, I have uploaded a mender artifact into a public file upload utility (FileChucker) and received the below URL with https:
[https://encodable.com/uploaddemo/?action=viewer&path=&file=ccu-2.mender](https://encodable.com/uploaddemo/?action=viewer&path=&file=ccu-2.mender)
- On device (i.e i.MX8DX6), I have stopped the mender daemon by following command (as per [https://docs.mender.io/1.7/architecture/standalone-deployments#setting-mender-up-for-standalone-mode](https://docs.mender.io/1.7/architecture/standalone-deployments#setting-mender-up-for-standalone-mode)):
_# systemctl stop mender_
- I have run the following command for updating the artifact (as per [https://docs.mender.io/1.7/architecture/standalone-deployments#deploy-an-artifact-to-a-device](https://docs.mender.io/1.7/architecture/standalone-deployments#deploy-an-artifact-to-a-device))
_# mender -rootfs [https://encodable.com/uploaddemo/?action=viewer&path=&file=ccu-2.mender](https://encodable.com/uploaddemo/?action=viewer&path=&file=ccu-2.mender)_
When I tried with the above procedure, I got the below error:
> _INFO[0000] Loaded configuration file: /etc/mender/mender.conf module=config_
> _INFO[0000] Mender running on partition: /dev/mmcblk0p2 module=main_
> _INFO[0000] Performing remote update from: [[https://encodable.com/uploaddemo/?action=viewer](https://encodable.com/uploaddemo/?action=viewer)]. module=rootfs_
> _**ERRO[0002] rootfs: error while updating image from command line: Will not continue with unknown image size. module=main**_
Could anyone help me to figure out what is wrong here and how to resolve this issue?

Hi,
I think the problem must be the ampersand in your command like argument. Please try with:
`mender -rootfs "https://encodable.com/uploaddemo/?action=viewer&path=&file=ccu-2.mender"`
Best regards,

Hi,
Actually, that is not really the URL of the file but only the URL of the website html.
You need to specify the file itself with:
`mender -rootfs "https://encodable.com/uploaddemo/files/ccu-2.mender"`
Best regards,
Lluís

Thank you so much @lluiscampos for the catch 👍
