Hi Mender team,

We are using i.MX8M Plus technexion EVK where we are following below link:

> **[Preauthorizing devices | Mender documentation](https://docs.mender.io/development/server-integration/preauthorizing-devices)**
>
> Mender documentation

While running mender-artifact command for copying the private key to sdimg, we are facing below error:

\*\*debugfs: error running command: “cd mender\nwrite /tmp/mender-artifact-install162466796/1private.key mender-agent.pem\nclose”, err: \*\*  
**do\_write\_internal: Permission denied while opening “/tmp/mender-artifact-install162466796/1private.key” to copy**  
**write: Permission denied**

Can you please help us identify the root cause of this issue?

Regards,  
Kunal

Hi Mender Team,

Just to add I am using latest mender version and downloaded the utility directly (not compiled from source).

Hi Mender Team,

I was able to solve the issue. It was a permission issue. Meanwhile, can anyone guide me on how to install multile files to sdimg by running mender-artifact command only once?
