I started a new project in Symfony 5 and i tried to install EasyAdmin with composer require easycorp/easyadmin-bundle but I found an issue.

Composer log :

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "5.1.*"
Your requirements could not be resolved to an installable set of packages.

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 :)

Please explain what you've changed and why. Also, you should not run composer using sudo unless you have a good reason to do so
I`ve changed version of doctrine: "doctrine/orm": "^2.6.3", and added: "easycorp/easyadmin-bundle": "3.1", Then necessarily do update of the composer.
Please add all such explanation to your answer by editing it

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.

Thank you for your help, it was evident finally ! But when I try to upgrade, there are issues with other dependencies ...
If there are other problems on upgrading, please open a new question for this

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"
