I’m using Mender 2.0 and trying to install a package on raspberry creating an artifact with following command

```
# DEVICE_TYPE="raspberrypi3"
# ./mender-artifact-3 write module-image -t $DEVICE_TYPE -o ./output/20190430-install-ntp.mender -T shell-command -n 20190430-install-ntp -f ./input/install.sh

```

install.sh file has following content

```
#!/bin/bash
sudo apt-get -y install ntp

```

I create a deployment and this is error log

```

```

Raspberry stops working and it is not reachable anymore.  
Any suggestion?

Thank you  
Best regards

This message is output when the client starts, and is an indication that Mender was restarted as part of what happened in the update module. This is treated by the client as an error and results in a failed update. Can you think of anything in your script that would kill the mender process?

I think the problem was due to command output.  
I changed install.sh script to

```
#!/bin/bash
sudo apt-get -qq install ntp > /dev/null

```

and it works like a charme

I’m going to continue this discussion because of another issue I’ve found

I develop a “shell-command” script to update content of a file using following script

```
#!/bin/bash
touch /usr/share/mender/modules/v3/install-update
cat > /usr/share/mender/modules/v3/install-update << 'ENDOFFILE'
#!/bin/bash

set -e

STATE="$1"
FILES="$2"

# working directory for update
update_dir="/tmp/update"

# files for backup
prev_files=/tmp/prev.tar

# file containing new version
update_file="$FILES"/files/update.tar

Hi @zumiani,

I still don’t see the problem.

This should be the Update Module error:

```auto
Update module output: /usr/share/mender/modules/v3/shell-command: 12: /usr/share/mender/modules/v3/shell-command: /var/lib/mender/modules/v3/payloads/0000/tree/files/update-script.sh: not found

```

However, I don’t see in your Update Module where do you call `update-script.sh`. Clearly not in line 12.

Are you sure that you are posting the right code for the module?

Dear @lluiscampos,

I’m using “shell-command” topic included in Mender 2.0 to update files

Hi @zumiani,

There is a misunderstanding here. You are writing your own Update Module, named `install-update`, but then your Artifact is for another module, `shell-command`(\*). This is wrong, the Artifact shall have the type of the Update Module that needs to handle it.

You need to change your `mender-artifact` options to use `-T install-update`.

(\*) Side note, `shell-command` module has been renamed to `script` from the beta to the final 2.0 release

Dear @lluiscampos,  
I’m calling shell-command topic. This script should run as each file included in mender artifact. File in mender artifact is called update-script.sh

Hello @zumiani

Okey, I think I finally understood what are you doing. Your script is trying to create other Update Module called `install-update`, and there is where I got confused before. Sorry.

I cannot see any obvious error. The `update-script.sh` file should be there…

If you have remote access to the device, I would try to install this Artifact in standalone mode, so that you can debug a bit. In standalone mode, the file tree will be present in `/var/lib/mender/...` between install and commit/rollback, so then you have the chance to inspect and manually run the script.

I tried to manually copy update-script.sh to /var/lib/mender/modules/v3/payloads/0000/tree/files/update-script.sh and run it from there.  
It works like a charm.

Which try do you suggest to perform?

Good. So there must be something related to the Artifact or to the `shell-command` Update Module (that, as I said, is deprecated and you should use the `script` one, but that cannot be the issue).

What I suggested is:

- First eliminate that script that you have manually created at `/var/lib/mender/.../update-script.sh`
- Eliminate also the Update Module that you have probably created when running the previous script (the file at `/usr/share/mender/modules/v3/install-update`)
- Copy the Artifact to the device with scp
- Run `mender -install filename`, where filename is the name of the Artifact
- Now, that should fail at this point. Please copy us here the output.
- And depending on the error situation, the payload tree at `/var/lib/mender/...` might be there, so run a `find` command on there and copy us here the output

Here is command output.  
I have changed mender-client to production version 2.0.0 (no more beta)  
I have created a symlink from “script” to “shell-command”

And after the error, can you check if the file is actually there in `/var/lib/mender/modules/v3/payloads/0000/...`?

Hi @zumiani

I think I found the problem. The `updatev2` script has Windows-like line endings CRLF, so when executing on the Raspberry Pi it will actually error with:

```auto
./updatev2: /bin/bash^M: bad interpreter: No such file or directory

```

I don’t know, however, how you managed to execute it locally, maybe you were using `bash updatev2` instead of just `./updatev2` ?

For a Linux script, you must use Unix endings. Please modify your script, repack the Artifact, and retry. Tip: you can use `dos2unix` tool for this.

Dear @lluiscampos,  
that was the problem!  
I’ve converted file using the tool you suggest and everything works fine.

Thank you very much for your assistance!
