Angular 6 CLI issue

After installing the new Angular 6 CLI, I was eager to try it out. So I opened up a command prompt and invoked ng new MyNewAngular6App.

But instead of getting a new Angular project, I got the following error message:

Schematic input does not validate against the Schema: {"dryRun":false,"version":"6.0.4","skipGit":false,"skipInstall":false,"linkCli":false,"commit":true,"newProjectRoot":"projects","inlineStyle":false,"inlineTemplate":false,"routing":false,"prefix":"app","style":"css","skipTests":false}
Errors:

  Data path "" should NOT have additional properties(dryRun).
I talked to a collegae who installed Angular 6 before and he didn’t had the same problem. While comparing our projects I noticed that he had an older version of the Angular CLI; 6.0.3 where I was using the 6.0.4 version. So this looks like an issue specifically linked to Angular CLI 6.0.4.
I tried to downgrade to 6.0.3 after which ng new finally worked:

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@6.0.3

Remark: The Angular team is already aware of this issue and did a new release 6.05 which is a rollback to 6.0.3, https://github.com/angular/angular-cli/releases/tag/v6.0.5
