Hi Team, I am getting below error while launching tutor locally using command “sudo tutor local launch”. error:- docker compose -f /home/myLaptop/.local/share/tutor/env/local/docker-compose.yml -f /home/myLaptop/.local/share/tutor/env/dev/docker-compose.yml --project-name tutor\_dev stop validating /home/myLaptop/.local/share/tutor/env/dev/docker-compose.yml: services.cms.volumes array items[0,6] must be unique Error applying action: func=\ contexts=’ Error: Command failed with status 15: docker compose -f /home/myLaptop/.local/share/tutor/env/local/docker-compose.yml -f /home/myLaptop/.local/share/tutor/env/dev/docker-compose.yml --project-name tutor\_dev stop ---

Hi, it relates to docker compose version. Please see [docker compose validations fail with docker-compose-plugin \> 2.21 · Issue #992 · overhangio/tutor · GitHub](https://github.com/overhangio/tutor/issues/992). Furthermore, why are you using sudo to run tutor? Ideally, you should not do it to run tutor. It should run without it. ---

Actually, I believe the error comes from some incorrect volume configuration: > validating /home/myLaptop/.local/share/tutor/env/dev/docker-compose.yml: services.cms.volumes array items[0,6] must be unique Can you paste here the content of `/home/myLaptop/.local/share/tutor/env/dev/docker-compose.yml`? Also, please follow Dawoud’s suggestion to not run as root. ---

This previous weekend, I encountered this same problem (_error code 15 for yaml files_) with a brand-new Tutor Open edX instance ( **Palm 4** release, **v16.1.8** ). After extensive troubleshooting over two days, on the _Docker_, _Tutor_, _Openedx_ forums, _Stackoverflow_ and respective _Github_ repo issues it seems the root cause is a compatibility issue with **Docker’s latest version** , likely originating from **v25**. I tested the YAML configuration files and found no errors. These tests also included fresh installations on both _Ubuntu **20** and **22** _, while other dependencies, software, networking, system resources being controlled/monitored, each performed twice. The issue appears to be specifically related to the `./dev/docker-compose.yml` file. When executing ‘docker compose up’ on the `./local/docker-compose.yml` file, there are no conflicts, and the build process initiates smoothly. I would recommend trying with Docker **v24** (I successfully installed it using **24.0.7-1~ubuntu.20.04~focal – on a VM** ). Although further extensive troubleshooting and confirmation from more experienced professionals, such as yourself, Regis, would be beneficial.
