I have Raspberry Pi set up by following the [board integration](https://hub.mender.io/t/raspberry-pi-3-model-b-b-raspbian/140), pi booted up, everything is great, but…

But when I try to install artifact I am facing following issue:  
“INFO[0000] no public key was provided for authenticating the artifact module=installer  
ERRO[0000] Reading headers failed: installer: failed to read Artifact: readHeaderV3: handleHeaderReads: Cannot load handler for unknown Payload type ‘rootfs-image’ module=standalone  
ERRO[0000] installer: failed to read Artifact: readHeaderV3: handleHeaderReads: Cannot load handler for unknown Payload type ‘rootfs-image’ module=main”

Could someone please let me know what I am missing

EDIT: I created disk image run and this time it worked. Not really sure what went wrong the first time as I was using same docker container to run mender-convert

I believe you are using standalone mode in your example. If yes, could you please try with `-debug` option along with your mender command to get more details (Ex: `mender -debug -install <URI>`)?
