I am looking for information regarding the mender client reto-compatibility. During an update, the first part of the update (install) will be done in the initial system version (orgin). The second part (commit) will be done in the upgraded version of the system (target). This means that the mender …

Hi @Chris and thank you for your report. We seem to have a regression for standalone mode. I have reported it now in our bug tracking system and we will be working on a fix ASAP. As Josef pointed out, this bug is not related to the major bump in the version. We do design Mender client exactly as y…

Hi @Chris , The Mender Client does not roll back based on versions or such, so the first thing to check is if there was an additional reboot between the origin and the target version. Depending on your exact setup, inspect the bootcount and upgrade_available variables before invoking mender-update c…

Hi Josef, Thanks for your answer. The environment is correct (bootcount=1,upgrade_available=1). This happens systematically when using 5.0 and never when using 3.3/4.0. Here is the log for 5.0: $ sudo mender-update -l trace commit record_id=1 severity=trace time="2024-Nov-28 15:32:15.697540" nam…

Hi @Chris , There is a breaking change, otherwise per semantic versioning it would have been a 4.x. This is it: https://github.com/mendersoftware/mender/commit/5b9691ae17e4b3d8724978bb5e809e7af9b8b9c6: the docker, script, deb and rpm Update Modules are moved out of the default installation. But you…

Hi Josef, I get the same behavior without any state scripts. $ sudo mender --version v3.3.0 runtime: go1.19.4 $ sudo mender -l trace install http://artifact-url.mender DEBU[0000] Reading Mender configuration from file /var/lib/mender/mender.conf INFO[0000] Loaded configuration file: /var/lib…

Same is happening between v4 and v5: $ sudo mender-update --version 4.0.4-dirty $ sudo mender-update -l trace install http://artifact-url.mender record_id=1 severity=debug time="2024-Dec-02 15:35:01.552291" name="Global" msg="No Bootstrap Artifact found at: /var/lib/mender/bootstrap.mender" recor…

Hi @Chris , Right from looking at it, I don’t know. I’ll try to reproduce but not sure how fast I get to it, sorry - this week the Yocto Project Summit is happening. Also poked the devs, hopefully it rings a bell for them. Last question for now, this is standalone mode, right? Greetz, Josef

Hi Josef, Thanks for your support and time. Yes it’s standalone. I did not yet give it a try through managed updates.

Hi Lluis, Thanks for the update. I’m glad and relieved to hear that there are no planned breaking change about that. Please let me know if your need any additional data or other kind of feedback. By the way, is there an approximate ETA for v5 ? Best regards, Chris

Hi @Chris I don’t have an ETA. We are working hard on getting it out ASAP :slight_smile: We fixed this regression (and added a test for it). Please repeat your tests with 5.0.0-build7 release candidate. Lluis

Hi Lluis, I can confirm that the issue is fixed in 5.0.0, updating from 3.3.0. Thanks!
