I can’t upload signed artifacts via GUI. Integration is on V2.0.0 and `mender-artifact` is on v.3.0.1. Artifacts are created using mender-artifact from .ext4. I don’t use `--version` with mender-artifact, so it should use artifact V3 I suppose. `mender-deplyments` container throws these errors: > **logs from mender-deplyments** > > ``` > time="2019-07-12T14:51:22Z" level=error msg="reading artifact error: readHeaderV3: handleHeaderReads: readHeader: readNext: Failed to copy from tarReader to the writer: unexpected EOF: Cannot parse artifact file" file=images.go func="controller.(*SoftwareImagesController).NewImage" line=239 request_id=bd965f2e-eb8a-41cb-b0b9-564699d67c8f user_id=5ec43064-1fe1-49bd-92b2-c3a7ee220460 > time="2019-07-12T14:51:22Z" level=error msg="reading artifact error: readHeaderV3: handleHeaderReads: readHeader: readNext: Failed to copy from tarReader to the writer: unexpected EOF" file=view.go func="view.(*RESTView).RenderError" line=51 request_id=bd965f2e-eb8a-41cb-b0b9-564699d67c8f user_id=5ec43064-1fe1-49bd-92b2-c3a7ee220460 > > ``` The problem only exists with signed artifact. This problematic artifact passes `mender-artifact validate` successfully. If the same artifact is generated without `--key` argument, it can be uploaded without any issue. I checked [docs about keys](https://docs.mender.io/2.0/administration/certificates-and-keys) and it doesn’t seem that I should somehow provide Server with any artifact keys. What have I missed? Also, little UX flaw: when this error happens, GUI shows nothing, the upload progress bar just getting stuck at random between 4% and 10%. It should probably notify the user that something went wrong. ---

Can you share the commands you use to create the Mender Artifact. I tried to reproduce but was not successful, it uploaded just fine. Though I was using Hosted Mender but should be equivalent to v2.0.0. ![Screenshot_2019-07-12_18-06-09](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/09607c761140cb2e789ce2688c785f90a249f2c8.png) ---

Sure: ``` mender-artifact --compression "lzma" write rootfs-image --file "$releaseName-mender.ext4" --device-type "raspberrypi3" --artifact-name "$releaseName-mender" --output-path "$releaseName-mender.mender" --script "$scriptsDir/ArtifactInstall_Enter_01_retain_wpa_supplicant" --key "$pathToSignKey" ``` The command to generate unsigned artifact is the same but without `--key`. I regenerated signed artifact once again and still have the issue. ---

Thanks, now I can see it as well. It seems to work if you remove `--compression "lzma"`. Can you confirm this as well? ---

@ster, could you give the version of `mender-artifact` that you are using? ---

As mentioned in the first message, I used `mender-artifact` **V3.0.1** , precompiled Linux binary downloaded from [here](https://d1b0l86ne08fsf.cloudfront.net/mender-artifact/3.0.1/mender-artifact) ---

Apologies! That was weak. However, I am still not able to reproduce this. Downloaded the binary, and ran: ```auto mender-artifact --compression "lzma" write rootfs-image --file test.img --device-type "raspberrypi3" --artifact-name release-1 --output-path test.mender --key ~/mendersoftware/integration/keys/deviceauth/private.key ``` ---

That is with hosted mender, and the demo environment locally. I am not doubting that you are having issues, just to be clear, so bear over with me. I will have a look at the backend ---

Maybe the keys are the key? 🙂 I use RSA with length of 3072 bits ---

So is the key in the integration repo 😕 I also, just to be sure, did convert the raw image to an ext4 image, to no avail. @kacf, perhaps you have some ideas here? ---

You are also missing a state script in your command, which the original command had to reproduce ---

I’ve tried both with and without scripts, still works. Tomorrow I will make a bash script to run the whole thing, so that we can standardize this 🙂 ---

For additional reference, when I performed my test I downloaded this image, [https://d1b0l86ne08fsf.cloudfront.net/2.0.1/raspberrypi3/raspberrypi3\_release\_1\_2.0.1.mender](https://d1b0l86ne08fsf.cloudfront.net/2.0.1/raspberrypi3/raspberrypi3_release_1_2.0.1.mender) Unpacked it, and then created a Mender Artifact with the mentioned command using the files from the extracted Artifact ---

@oleorhagen, I used your script with the only difference that I used GUI instead of `mender-cli` to upload the artifact and the issue is present, with the same logs from `mender-deployments`. One additional thing is that I have relatively low upload speed with my ISP (1-2 Mbit/s), maybe this could play the role? Here I uploaded `test.mender` (result of your script) I have issues with, can you try this file?
