admin panel - not able to enter access keys and save config

[Hy0Pi61]

Hi,

after finishing the magento 2 installation and adding sample-data via composer successfully on my local ubuntu server, i try now to check out the admin panel via => system => setup wizard => system configuration.

After entering the requested public and privat access keys, i just see an endless spinning wheel. Nothing else happens !

The firebug-console shows as soon as i enter the config page ( myIP/magento2/setup/#/system-config):

"POST check-auth - 500 internal server error - 192.168.178.40 ... ... ...

The link behind this message is:

http://192.168.178.40/magento2/setup/index.php/marketplace/check-auth

Then I enter the accesskeys and press "save config". I see just the "spinning wheel /please wait" and the browser-console shows:

POST http://192.168.178.40/magento2/setup/index.php/marketplace/save-auth-json

GET http://192.168.178.40/magento2/setup/index.php/marketplace/index.php/session/unlogin

and

"NetworkError: 404 Not Found - http://192.168.178.40/magento2/setup/index.php/marketplace/index.php/session/unlogin"

Other setups (e.g. setting to a single store) seems to work.

Any idea about that ?

If you got "500 internal server error" then you shuld see the var/log folder for errors.

Thanks for your help !

I checked the log-files, but there was no error. Then I found with the help of firebug, that several error messages were basicly caused by the access to auth.json.

After switching the permissions from "-rw-------" to "-rw-r-----",  error 500 disappeared and now i can get also to "component manager" and "system upgrade", which shows me :"Sorry, we can't take that action right now", but this maybe is another issue or is it caused by currently none available upgrades ?

i get the same Problem at the Web Setup Wizard. I created the access keys at https://developer.magento.com in my account. Its enabled.  So it might work.

Then i fill the keys in the fields at the Web Setup Wizard. After clicking "Save config" the Spinning Wheel appears and nothing happened after that.

I Use Magento 2.1.0 Community Edition.

Additional there appeared errors after clicking "inspect":

Do you have any Idea how to fix that?

Thanks a lot and kindly regards
