Harbor `./prepare` error on Ubuntu 24.04

[mehdiMj-ir]

Expected behavior and actual behavior: I have installed new Ubuntu Server 24.04 on my ESXi 8 with Docker CE 27.3.1 and expected to run Harbor with no problem but I'm getting error while ./prepare the service.

Steps to reproduce the problem: Install Ubuntu 24.04 and Docker CE and try to install harbor online installation.

Versions:

• harbor version: [2.12.0]
• docker engine version: [27.3.1]
• docker-compose version: [v2.29.7]

Additional context: It was looking for python 3.11 but the default python version on Ubuntu 24.04 is 3.12.3 so I tried to install python 3.11 via PPA and set as primary using update-alternatives but didn't work

root@my-server:/opt/harbor# ./install.sh --with-trivy

I think it's looking for docker-compose which it doesn't installed by default and docker uses docker compose instead! I know it can be installed standalone but It would be better If it can work with docker compose too.

How do you install your docker? Have you install the docker via apt get?

[mehdiMj-ir]

Yes, I just copy and paste commands from docker documentations

[mehdiMj-ir]

Sorry, I double checked my grep command and I should have put it between ", but beside that I still have issue

[MinerYang]

it should work with 'docker compose'. Do you still have the same error msg pasted above? if so could you provide your harbor.yaml file, and kindly check if it is with correct yaml syntax.
