I forked a repository to my GitHub account (fiSCIENCES), but when I do ‘composer update’ I get:

Loading composer repositories with package information                                                                                                                                                                                                            Updating dependencies                                 
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires fisciences/yii2-select-google-map-location, it could not be found in any version, there may be a typo in the package name.

I added my new forked repository to my composer.json:
(I had to remove the uppercase letters in my repository name, complained by composer)

"require": {
...
    "fisciences/yii2-select-google-map-location": "*"
},
...
"repositories": [
...
    {
        "type": "vcs",
        "url": "https://github.com/fisciences/yii2-select-google-map-location"
    }
]

Does it have something to do with uppercase letters in my repository name?
Or I miss something else?

Thank you.
