Hello all,  
I’m on mender-client version `2.2.0 runtime: go1.11.5` and would like to have the device that is running mender reboot on failure. My current state machine for `/usr/share/mender/modules/v3/deb` is the following:

```
#!/bin/sh
set -e

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

case "$STATE" in
    ArtifactInstall)
        yes | dpkg -i "$FILES"/files/*.deb
        ;;
    NeedsArtifactReboot)
        echo "Automatic"
        ;;
    SupportsRollback)
        echo "Yes"
        ;;
    ArtifactRollback)
        ;;
    ArtifactRollbackReboot)
        ;;
esac
exit 0

```

I’ve tried a few various setups in addition to this, including changing `Needs Reboot` from `Automatic` to `Yes`, having a reboot occur in ArtifactRollback (that didn’t go well), etc. Is there a way to guarantee that the device is rebooted always? On success and failure? I’ve observed that a lot of issues arise around dpkg locks, and rebooting is the most reliable way to resolve it.

I’m also OK with updating to a newer mender-client if need be.

Thanks!

Hi @lizziemac I _think_ what you want here is to use an ArtifactFailure state script rather than modifying the update module. Assuming the actual dpkg command fails the new package will _not_ have been installed and no rollback is necessary.
