Laravel 5.2 - Cant install - Conclusion: remove symfony/finder v3.0.7

[simplenotezy]

I am getting the following error when I install on a Laravel 5.2 project.

vagrant@homestead:~/Projects/project$ composer require vinelab/cdn:dev-master
./composer.json has been updated
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
    - Installation request for vinelab/cdn dev-master -> satisfiable by vinelab/cdn[dev-master].
    - Conclusion: remove symfony/finder v3.0.7
    - Conclusion: don't install symfony/finder v3.0.7

Rollback to the 2.* branch.

composer require "symfony/console:^2.8"
composer require "symfony/finder:^2.8"
composer require "vinelab/cdn"
