When updating Laravel to a major version, it might be straightforward but more often than not, it is not. Most of the time the error message boils down to something similar to the following excerpt: Running composer update laravel/framework --with-all-dependencies Loading composer repositories with package information Updating dependencies Your requirements could not be resolved to an installable set of packages.
Example for the current installed version: The next major version correctly supports our target: Why lowest, you might ask?
Then I try to update the update the whole thing: composer update --with-all-dependencies spatie/laravel-fractal laravel/framework
Sometimes, during such a major upgrade, I need to adjust the locked dev dependencies versions as well.
