Do you have an idea to resolve it ?

Easyadmin has a dependency on doctrine/common v2 you need to remove your current doctrine version with composer remove doctrine/common then you can install easyadmin

Try change your composer.json file like this:

    "type": "project",
    "license": "proprietary",
    "require": {
        "php": ">=7.2.5",
        "ext-ctype": "*",
        "ext-iconv": "*",
        "composer/package-versions-deprecated": "^1.11",
        "doctrine/annotations": "^1.10",
        "doctrine/doctrine-bundle": "^2.1",
        "doctrine/doctrine-migrations-bundle": "^3.0",
        "doctrine/orm": "^2.6.3",
    "easycorp/easyadmin-bundle": "3.1",
        "sensio/framework-extra-bundle": "^5.6",
        "symfony/asset": "5.1.*",
        "symfony/console": "5.1.*",
        "symfony/dotenv": "5.1.*",
        "symfony/flex": "^1.3.1",
        "symfony/form": "5.1.*",
        "symfony/framework-bundle": "5.1.*",
        "symfony/maker-bundle": "^1.20",
        "symfony/security-bundle": "5.1.*",
        "symfony/stopwatch": "5.1.*",
        "symfony/twig-bundle": "5.1.*",
        "symfony/validator": "5.1.*",
        "symfony/web-profiler-bundle": "5.1.*",
        "symfony/yaml": "5.1.*",
        "twig/extra-bundle": "^2.12|^3.0",
        "twig/twig": "^2.12|^3.0"
    },

and then type: sudo composer update. Works on Ubuntu 18.04 LTS :)

As you can see in that list of error messages: easycorp/easyadmin-bundle requires doctrine/common in v2, while you have already installed v3.

You should downgrade that package such that the admin bundle can be installed. If you need help with that, please add the content of composer.json to your question.

You need to downgrade doctrine/common and doctrine/persistence.

Try this:

composer require doctrine/persistence:1.3.8 doctrine/common:2.13.3

Then you should be able to call:

symfony composer req "admin:^2.0"
