Updating core to 8.9.6 fails

I’v installed Drupal 8 by composer. Everything worked fine, but when I tried to update core from 8.9.1 to 8.9.5 in ended up in 8.9.4.

Today I tried to update from 8.9.4. to 8.9.6 by changing composer.json to demand v 8.9.6 at least.

The result was following error message:

Your requirements could not be resolved to an installable set of packages. Problem 1

  • Installation request for symfony/http-kernel (locked at v3.4.41) -> satisfiable by symfony/http-kernel[v3.4.41]. > – drupal/core-recommended 8.9.6 requires symfony/http-kernel v3.4.44 -> satisfiable by symfony/http-kernel[v3.4.44]. > – drupal/core-recommended 8.9.x-dev requires symfony/http-kernel v3.4.44 -> satisfiable by symfony/http-kernel[v3.4.44]. > – Conclusion: don’t install symfony/http-kernel v3.4.44 > – Installation request for drupal/core-recommended ^8.9.6 -> satisfiable by drupal/core-recommended[8.9.6, 8.9.x-dev].

I’m stuck, since I don’t know what locks symphony/http-kernel to v3.4.41.

I’m still pretty new with composer and would be glad if anybody could help me. Thanks a lot.

My update command was

composer u drupal/core* --with-dependencies
