I am currently trying to upgrade my site from drupal 8.9 to drupal 9. I ran these commands to give permissions:
$ chmod 777 web/sites/default
$ find web/sites/default -name "*settings.php" -exec chmod 777 {} \;
$ find web/sites/default -name "*services.yml" -exec chmod 777 {} \;
Then I required the the recommended project for drupal 9 and also the dev:
$ composer require drupal/core-recommended:^9.0.0 drupal/core-composer-scaffold:^9.0.0 drupal/core-project-message:^9.0.0 --update-with-dependencies --no-update
$ composer require drupal/core-dev:^9.0.0 --dev --update-with-dependencies --no-update
All my modules are up to date and I also ran upgrade status to check for errors. I got one error, which was in tests (I guess that would be OK?) and a couple of warnings for a library that wasn't installed.
Then I ran
$ composer update
and got the following errors:
