I am having a little trouble updating to 11.3.0 this morning, which was just released so maybe there is a composer repository issue. Something to do with core-composer-scaffold.

composer require drupal/core-recommended:11.3.0 drupal/core-composer-scaffold:11.3.0 -W

Your requirements could not be resolved to an installable set of packages.Problem 1- Root composer.json requires drupal/core-composer-scaffold 11.3.0 (exact version match: 11.3.0 or 11.3.0.0), found drupal/core-composer-scaffold[8.8.0-alpha1, ..., 8.9.x-dev, 9.0.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.6.x-dev, 11.0.0-alpha1, ..., 11.x-dev] but it does not match the constraint.Problem 2- Root composer.json requires drupal/core-recommended 11.3.0 -> satisfiable by drupal/core-recommended[11.3.0].- drupal/core 11.3.0 requires drupal/core-composer-scaffold 11.3.0 -> found drupal/core-composer-scaffold[8.8.0-alpha1, ..., 8.9.x-dev, 9.0.0-alpha1, ..., 9.5.x-dev, 10.0.0-alpha1, ..., 10.6.x-dev, 11.0.0-alpha1, ..., 11.x-dev] but it does not match the constraint.- drupal/core-recommended 11.3.0 requires drupal/core 11.3.0 -> satisfiable by drupal/core[11.3.0].

why-not?

ddev composer why-not drupal/core-composer-scaffold 11.3.0

my/repo dev-main requires drupal/core-composer-scaffold (11.2.8)Not finding what you were looking for? Try calling `composer require "drupal/core-composer-scaffold:11.3.0" --dry-run` to get another view on the problem.

That wasn’t helpful.

Yes, I use exact versions in my composer.json It’s fine. Deal with it.

Installing 11.3.0-rc2 works.

composer require drupal/core-recommended:11.3.0-rc2 drupal/core-composer-scaffold:11.3.0-rc2 -W

I’ll try again in a couple of hours. This might be a d.o infrastructure issue. Nothing mentioned in Drupal Slack so far.
