I'm currently working on upgrading a Drupal site from Drupal 8.9.7 to Drupal 9.
I'm getting this error when I run lando composer require "drupal/core:^9.3.8" --with-all-dependencies.
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires overtrue/phplint ^0.2.4 -> satisfiable by overtrue/phplint[0.2.4].
- drupal/core-recommended[9.3.8, ..., 9.4.x-dev] require symfony/yaml v4.4.34 -> satisfiable by symfony/yaml[v4.4.34].
- Conclusion: don't install symfony/yaml v4.4.34 (conflict analysis result)
- Root composer.json requires drupal/core-recommended ^9.3.8 -> satisfiable by drupal/core-recommended[9.3.8, 9.3.x-dev, 9.4.x-dev].
Installation failed, reverting ./composer.json to its original content.
The content of the composer.json is the following.

I'm really at a loss at this point any help would be appreciated.
