Update from 8.5.0 to 8.5.1 is failing on one of my drupal instance.
>composer update drupal/core --with-dependencies Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested package symfony/debug (locked at v4.0.6, required as ^3.4.0) is satisfiable by symfony/debug[v4.0.6] but these conflict with your requirements or minimum-stability.
What does this mean? What should I do?
PS: Please find below some more related information
