Wortlaut der Fehlermeldung

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- The requested package roave/security-advisories (locked at dev-master) is satisfiable by roave/security-advisories[dev-master] but these conflict with your requirements or minimum-stability.

<warning>Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.</warning>
Finished Composer Cloud resolving.
