I had the same problem when I build my project on gitlab CI, my workaround was to change my composer.lock. I remove "url": "git@github.com:mustangostang/spyc.git" and put "url": "https://github.com/mustangostang/spyc.git"

The problem comes back using composer update

@diogolast this is also a quick fix in your composer.json, which works with composer update
