Hi @lluiscampos ,

Im using this Module to update a Azure repo,  
I’m getting this unauth error, I have logged into docker and azure creds, But still I get this:

**WARNING: Error loading config file: /home/mender/.docker/config.json: stat /home/mender/.docker/config.json: permission denied**  
**Error response from daemon: Get https:/azurecr.io/manifests/4.1: unauthorized: authentication required, visit [https://aka.ms/acr/authorization](https://aka.ms/acr/authorization) for more information.**

This is how I’m trying to create the release :,  
ARTIFACT\_NAME=“load-update-1.0”  
DEVICE\_TYPE=“cam”  
OUTPUT\_PATH=load-container-update-1.0.mender  
DOCKER\_IMAGES=“[0.azurecr.io/load/local:.1](http://0.azurecr.io/load/local:.1)”  
./docker-artifact-gen -n {ARTIFACT\_NAME} -t {DEVICE\_TYPE} -o {OUTPUT\_PATH} {DOCKER\_IMAGES}

But when I give **sudo ./docker-artifact-gen -n {ARTIFACT\_NAME} -t {DEVICE\_TYPE} -o {OUTPUT\_PATH} {DOCKER\_IMAGES** }, then error goes away, and It starts pulling the image, but at the end I get **“Required flag " f” not set"**

Please tell me, what is that Im doing wrong here

FYI: I’m able to docker pull normally, so why is this giving error

Hello @nishad1092,

Once you are logged in into the Docker Registry (via `docker login`), the script `docker-artifact-gen` should be able to pull the image without requiring `sudo`. Actually, using `sudo` will make the script not to be able to pull the image…

Try to pull manually the image before running the script and post us here your results:

```auto
docker pull 0.azurecr.io/load/local:.1
./docker-artifact-gen -n ${ARTIFACT_NAME} -t ${DEVICE_TYPE} -o ${OUTPUT_PATH} ${DOCKER_IMAGES}

```

Note: All shell variables require a “`$`” symbol!

I did pull manually and tried doing the same, but still the error exist:

</div>

@nishad1092 Is that the output from the `docker pull` command or the `./docker-artifact-gen` one?

Also, there is a very suspicious typo there: “stat /home/mende/.docker/config.json” -\> shouldn’t it be `mender` ?

@nishad1092 Check that the file exists and that it has the correct permissions with:

```auto
stat /home/mende/.docker/config.json

```

Hi @lluiscampos,

It is the output from ./docker-artifact-gen -n {ARTIFACT\_NAME} -t {DEVICE\_TYPE} -o {OUTPUT\_PATH} {DOCKER\_IMAGES}

and the err msg is:  
Error loading config file: /home/mender/.docker/config.json: stat /home/mender/.docker/config.json: permission denied  
Error response from daemon: Get [https://0.azurecr.io/v2/c/local/manifests/4.0.1:](https://0.azurecr.io/v2/c/local/manifests/4.0.1:) unauthorized: authentication required, visit [https://aka.ms/acr/authorization](https://aka.ms/acr/authorization) for more information.

There is a config.json file in that location and also it has a content which mentions:

```
{
        "auths": {
                "0.azurecr.io": {
                        "auth": "xxxxxxxxxxxxxxxxxxxx"
                }
        },
        "HttpHeaders": {
                "User-Agent": "Docker-Client/19.03.6 (linux)"
        }
}

```

And it has root root permission for both user and group

</div>

I got:

stat: cannot stat ‘/home/mender/.docker/config.json’: Permission denied

It has root permission, Should I change it to mender perm for user and group?

Change the permissions to what ever user you are running as, e.g you can run:

```
$ id

```

To find this out. The docker commands in the script are run as a regular user as you can see [here](https://github.com/mendersoftware/mender/blob/master/support/modules-artifact-gen/docker-artifact-gen#L111-L112). This is why `sudo ./docker-artifact-gen ...` does not help

Also it is probably best to update your docker permissions so you do not need sudo (which I think is the root problem),

Hi @mirzak, @lluiscampos  
I changed the permission of that config.json to the current user i use, and I ran

./docker-artifact-gen -n {ARTIFACT\_NAME} -t {DEVICE\_TYPE} -o {OUTPUT\_PATH} {DOCKER\_IMAGES}  
but I got this error this time,

./docker-artifact-gen: line 116: meta-data.json: Permission denied

Hi @mirzak,

Thanks for taking this issue as a seperate branch topic.

So this is what I get now. After giving perm to /home/mender/.docker/config.json, the previous error is gone but got this new permission denied.

First time having perm issue while creating a artifact

@nishad1092 Then just remove the old meta-data file with:

```auto
sudo rm meta-data.json 

```

and try again 🙂

@nishad1092 Mmm. Which version of `mender-artifact` are you running? Can you do:

```auto
mender-artifact --version

```

and copy here the output?
