Hi,

I am using mender server version 2.1.0.  
when I do deployment, its get successful.I can see my device gets booted with new version. Mender server also shows updated version for my device. But it shows deployment status as “Failure”.

@drewmoseley any idea what will be the issue here?

Hi @Rohita83 it seems that something is causing an extra reboot on the client. This part of the log seems to indicate this:

```
{“level”:“info”,“message”:“Rebooting device(s)”,“timestamp”:“2020-11-02T04:59:33-05:00”}
{“level”:“info”,“message”:“Mender rebooting from active partition: /dev/sda3”,“timestamp”:“2020-11-02T04:59:33-05:00”}
{“level”:“error”,“message”:“Error rebooting device: signal: terminated”,“timestamp”:“2020-11-02T04:59:33-05:00”}

```

We would need logging from the client to be able to understand why this happened. Can you provide full console logs as well as the output from “journalctl -u mender-client”?

I have the same problem.  
I believe the problem is because Mender is configured to use ttyS0, and som other tty connections. What these are used for, I haven’t been able to find out, but in my case after I removed ttyS0 from:  
`MENDER_GRUB_KERNEL_BOOT_ARGS="console=tty0,115200n8 console=ttyO0,115200n8 console=ttyAMA0,115200n8"`  
Then the update fails with the responds  
`2021-07-28 04:10:46 +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`

Any knowlagde to why mender-client needs ttyS0? @mirzak

No clue. Perhaps @lramirez can help here.

Got it to work.

Seems to be an problem with creating artifacts using the snapshot method, since creating artifacts over ssh works fine.

Hi. I have the same problem. Can you give me some more details?  
Thank you
