The web setup Wizard is not working, Welcome to Magento Admin, your online store headquarters.
To use the Magento setup wizard sign into your Admin account and navigate to System => Tools => Web Setup Wizard.
And when I try to upgrade trough composer I got
The "https://repo.magento.com/packages.json" file could not be downloaded (
HTTP/1.1 500 Internal Server Error)
what to do?
Authorization needed to see it. You can download magento 2.1.2, data migration tool and code migration toolkit at http://devdocs.magento.com/guides/v2.1/release-notes/ReleaseNotes2.1.2CE.html
I decided to use 1.9.x instead. There is too many things that still not working as you could expect in Magento 2.1.x.
