Answer 1

I had the same issue. I had to enable the mod_rewrite module and set the AllowOverride to all for /var/www/html directory in the apache configuration file.

Answer 2

Maybe a known issue? Some info regarding a work around currently as well.

https://github.com/magento/magento2/issues/254

According to that, this may fix it:

Quick fix: in app/code/Mage/Install/Model/Installer/Db.php:64 paste following

if($extName == 0) {
  continue;
}

after

foreach ($extensions as $extName) {

Answer 3

The problem is in getting of REQUEST_URI environment variable value and checking it withSCRIPT_FILENAME and SCRIPT_NAME environment variables values.

So a cause of the problem is in adding of /index.php/ prefix to the request path and the Magento url generation has this value hardcoded for admin.

Override method called _updatePathUseRewrites in /app/code/core/Mage/Core/Mode/store.php file : Replace this Function:

protected function _updatePathUseRewrites($url)
{
if ($this->isAdmin()    || !$this->getConfig(self::XML_PATH_USE_REWRITES) || !Mage::isInstalled()) {
$url .= basename($_SERVER['SCRIPT_FILENAME']).'/';        }
return $url;
}

with

    protected function _updatePathUseRewrites($url)
{
if ($this->isAdmin()    || !$this->getConfig(self::XML_PATH_USE_REWRITES) || !Mage::isInstalled()) {
$url .= '/';        }
return $url;
}

This will definitely solve your Problem
