Hi @Aysha,

without exactly knowing what you put into the Artifact, the only guess I can take is based on this line in the log

```auto
2023-08-04 09:54:22 +0000 UTC error: transient error: Reboot to the new update failed. Expected “upgrade_available” flag to be true but it was false. Either the switch to the new partition was unsuccessful, or the bootloader rolled back

```

So it seems that whatever is in that `container.tar.gz` that you tried to install is not properly handled. Even more guessing: it is not a full root filesystem, as you are talking about containers.

```auto
mender-artifact write rootfs-image

```

is meant for full system deployments. To create an Artifact for the `docker` Update Module, use the matching [generator script](https://github.com/mendersoftware/mender/blob/master/support/modules-artifact-gen/docker-artifact-gen), as mentioned in the already linked [tutorial](https://hub.mender.io/t/docker/324).

Greetz,
