Hey guys, i am going through the docker compose update tutorial for understanding and stucking right now at the update of the docker compose. I am at the tutorial on Step " Update your composition using delta " but there is an error after passing the app-gen command: ```auto app-gen --artifact-name "${ARTIFACT_NAME}-v2" \ --device-type "$DEVICE_TYPE" \ --platform "$PLATFORM" \ --application-name "$ARTIFACT_NAME" \ --image docker.io/library/traefik:v2.9,docker.io/library/traefik:v2.10 \ --orchestrator docker-compose \ --manifests-dir ./manifests/v2 \ --output-path artifact-v2.mender \ --deep-delta \ -- \ --software-name "${ARTIFACT_NAME}" \ --software-version "v2" \ --depends "rootfs-image.${ARTIFACT_NAME}.version:v1" ``` Getting error: ```auto declare -a images_shas=([0]="66c077549480f6828d39797ca3855e6299d0c1e7daf08d67cd62320c07515ff0" [1]="7bf33d2be1db3d2e3269b3f7952c276cbf9c1eaddc95c629257537490f8db2be") /home/mender/bin/app-gen: line 291: parent2id[null] not set. ``` Any thoughts about this? Creation manifest/v1 worked like a charme. I am using debian 12 as my workstation. ```auto Linux mender-dev 6.1.0-27-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.115-1 (2024-11-01) x86_64 GNU/Linux ``` ---

Hi @octaconnect, Thanks for the heads up! I could reproduce it, and the tutorial unfortunately doesn’t point out the required tools on the host. For manifest v1, respectively `app-gen` artifact creation without deltas, it is: - `jq` - `tree` For deltas, it is additionally - `xdelta3` - `docker-compose` (if you are using the `docker-compose` example) Greetz, Josef ---

Hm interesting, on my workstation and the device all packages are installed (jq, tree, xdelta3 and docker compose extension). I am using the extension docker compose (not docker-compose). Still not working and the same error return. ---

Hi @octaconnect, Please try to install docker-compose, and not just the extension variant. I don’t think that the app-gen script is fit for both variants. Greetz, Josef ---

I am having the same problem. I tried `sudo apt install docker-compose`, but it still did not work. And by the way, I cannot see that `docker-compose` is called anywhere in the `app-gen` script. Any help is appreciated! ---

**For people who encounter the same problem in the future, I found a solution:** My first problem was that I used `v1.0.0` of the application update module, since that is what the tutorial links to. However, newer versions of docker (\>= 25, I believe), create OCI-compliant images with `docker image save`, which requires `v1.1.0` of `app-gen` (simply replace all “1.0.0” in the tutorial with “1.1.0”). This allowed me to generate the artifacts in the tutorial. I got a new error when deploying the v2 artifact to my device: ```auto ERROR: current image is not in OCI format while the new one is, cant continue with deep delta. ``` It turns out that I had docker version \< 25 on my device (and that was the latest available version). I ended up installing an older version of docker on my workstation, and stuck to `v1.0.0` of the application update module. ---

Hi all, Adding a bit more onto this: I was also dealing with this problem until I found that version 1.0 of `app-gen` did not have the `oci_deep_delta` function. After upgrading from master I was able to generate the artifacts but not install the update. My issue differs from the one of the previously mentioned ones. When doing standalone deployment and calling the `mender-update install` command, I get some debug messages that go looking for the `sha246` directories. One, however, is not found: ```auto record_id=48 severity=info time="2025-Jan-09 19:12:29.766939" name="Global" msg="Update Module output (stderr): open /var/lib/docker/tmp/docker-import-3234564186/blobs/sha256/ac4d34842145233183135a3a3ddc7d2bf181b1da3023b6ca9627dd8ab946b73c: no such file or directory" ``` In my workstation, where the artifacts are generated, I use `docker inspect` on the versions 2.9 and 2.10 of `traefik`. This yields the following results: ```auto // traefik v2.10 "Layers": [ "sha256:ac4d34842145233183135a3a3ddc7d2bf181b1da3023b6ca9627dd8ab946b73c", "sha256:aebf07596a72256347e3562f09b0935d5be2cd71d1bdd1a97b4cfe08943582ee", "sha256:7a06da8012624d2e01eb6471bca70b99822c076797f26538ef3a6de258b6e6ea", "sha256:80a16eb735a4a805adf93d41b9e211c41712543608e086f7a9fe931cb8d1aaf5" ] ``` ```auto // traefik v2.9 "Layers": [ "sha256:bf3c9ec9aec09ee4ed7849f3515732f22b657cb1dedf14640187bfbb52e657bf", "sha256:c3a0102d2f55c8d2b7ed039faa5a5792702ef70f86c5ef1794adad3de329f9cf", "sha256:25de568ca4c4ad18588efd5f9fd11a3a07866ed309cd3b31123f2c8c46cd1715", "sha256:351769e383ad665c265e87e71446ba13c498dcded6d1034c2fd0da87e1a7328e" ] ``` We can see that the sha corresponding to the first layer of the new image is the sha of the directory that cannot be found, although a previous message shown during the installing indicates the layer is actually present: ```auto record_id=28 severity=info time="2025-Jan-09 19:12:29.056057" name="Global" msg="Update Module output (stdout): ./blobs/sha256/ac4d34842145233183135a3a3ddc7d2bf181b1da3023b6ca9627dd8ab946b73c.source" ``` I have ensured that my device in which the update is being deployed the latest modules are being installed. ```auto SRC_URI = "git://github.com/mendersoftware/app-update-module;branch=master;protocol=https" ``` Has anyone seen this error?
