My Linux had a Composer upgrade to Composer version 2.1.9. No problem with the newly set up Drupal. Only I still have an older Drupal lying around, which I now also wanted to update Composer 2 and Drupal 9.
I have now oriented myself to the following documentation: https://www.drupal.org/docs/develop/using-composer/preparing-your-site-for-composer-2
With a "composer update –dry-run" I get the following error message:
The "composer/installers" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.1.0"). You may need to run composer update with the "--no-plugins" option. The "cweagans/composer-patches" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.1.0").

Problem 1 - drupal-composer/drupal-scaffold[2.5.0, ..., 2.6.1] require composer-plugin-api ^1.0.0 -> found composer-plugin-api[2.1.0] but it does not match the constraint. - Root composer.json requires drupal-composer/drupal-scaffold ^2.5 -> satisfiable by drupal-composer/drupal-scaffold[2.5.0, ..., 2.6.1]. And if I now do what the error message also says "composer update –no-plugins":

I can’t jump back to the old composer 1 version so easily at the moment unfortunately, can I just manually adjust the composer.json now and what do I have to consider. Would be grateful for any help!
My current but outdated composer.json:
