MinervaNeue depends on MobileFrontend. However (if you have a MinervaNeue directory), the installer auto-enables MinervaNeue, but not MobileFrontend.
"PHP Fatal error: Uncaught Exception: MinervaNeue requires MobileFrontend to be installed. in /vagrant/mediawiki/includes/registration/ExtensionRegistry.php:267"
It should check for skin.json (where these requirements are defined), and if it exists, auto-enable the required dependencies (or don't auto-enable skins with such dependencies).
Tagging MinervaNeue for awareness, but I don't see an issue with the skin itself.
