Symfony 5.2 support issue

[AmineMissaoui]

Hello,
i have a problem with the installation in symfony 5.2, here's the error.

` Problem 1
- symfony/symfony[v2.3.33, ..., 2.8.x-dev] require doctrine/common ~2.4 -> found doctrine/common[2.4.0-RC1, ..., 2.13.x-dev] but the package is fixed to 3.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- symfony/symfony[v2.3.0-BETA1, ..., v2.6.1] require doctrine/common ~2.2 -> found doctrine/common[2.2.0BETA1, ..., 2.13.x-dev] but the package is fixed to 3.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- symfony/symfony[v2.3.24, ..., v2.7.4] require doctrine/common ~2.3 -> found doctrine/common[2.3.0-BETA1, ..., 2.13.x-dev] but the package is fixed to 3.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- astina/social-links-bundle dev-master requires symfony/symfony ~2.3 -> satisfiable by symfony/symfony[v2.3.0-BETA1, ..., 2.8.x-dev].
- Root composer.json requires astina/social-links-bundle dev-master -> satisfiable by astina/social-links-bundle[dev-master].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.`

Is there a fix?
Thanks in advance

Hello,
When I configure the bundle, I got this error: Required "app_id" key not supplied in config and could not find fallback environment variable "FACEBOOK_APP_ID" while the app_id is configured.
Do you have a solution?
