Cannot install any theme

Question

I am new to Drupal and am facing an issue where any theme that I try to install will fail with the following message:

Installing light_skeleton
An error has occurred.
Please continue to the error page

An AJAX HTTP error occurred.
HTTP Result Code: 403
Debugging information follows.
Path: /core/authorize.php/core/authorize.php?batch=1&id=4&op=do_nojs&op=do
StatusText: Forbidden
ResponseText: 
403 Forbidden
403 Forbidden
nginx/1.9.10

The root folder is owned by www-data:www-data and I have given the directory 775 permissions. I have also tried to give it a full access using chmod 777 but without success.

I have checked the logs of nginx and php but there are no errors displayed. The site itself, using the standard theme, works without any issues.

After getting the error, I get:

Notice: Undefined index: log in update_authorize_install_batch_finished() (line 291 of core/modules/update/update.authorize.inc).
Warning: Invalid argument supplied for foreach() in update_authorize_install_batch_finished() (line 291 of core/modules/update/update.authorize.inc).
Notice: Undefined index: log in update_authorize_install_batch_finished() (line 332 of core/modules/update/update.authorize.inc).
Notice: Undefined index: tasks in update_authorize_install_batch_finished() (line 333 of core/modules/update/update.authorize.inc).
Installation failed! See the log below for more information.

Answer 1

This is an nginx configuration issue and discussed intensely on this page Yet curiously no solid solution could be offered. Some guy on an other page proposed a solution. I applied that proposed solution and can confirm that in works!

To apply proposed solution go to your nginx configuration file under

/etc/nginx/sites-available/ directory on Ubuntu and add

rewrite ^/core/authorize.php/core/authorize.php(.*)$ /core/authorize.php$1;

just above the

location ~ \..*/.*\.php$ {
    return 403;
}

block. Location does matter!.. Restart your server:

sudo service nginx restart

and that's it. The problem solved!

Since you are getting a 403 response, it seems that Drupal is not giving you access for some reason. I haven't had any practical experience with this, but looking in the authorize.php, file I found this:

function authorize_access_allowed(Request $request) {
  $account = \Drupal::service('authentication')->authenticate($request);
  if ($account) {
    \Drupal::currentUser()->setAccount($account);
  }
  return Settings::get('allow_authorize_operations', TRUE) && \Drupal::currentUser()->hasPermission('administer software updates');
}

It seems that you could get an access denied response if:

• You don't have administer software updates permission.
• allow_authorize_operations is set to false. This would exist in your settings.php file AS $settings['allow_authorize_operations'] = FALSE;

Best guess is that it's the latter that might be your problem.
