Howto troubleshoot error after Drupal upgrade to 7.31, 7.32, 7.33, 7.34, 7.35, 7.36, 7.37, 7.38, 7.39 (Notice: Undefined index)
After the the upgrade to the recent Drupal version (in our example Drupal 7.31 - 7.34) you might get one of these errors: Notice: Undefined index: name in system_requirements() (line 34 in ../modules/system/system.install) or Notice: Undefined index: version in system_requirements() (line 36 in ../modules/system/system.install), solution is the same! This howto shows you how to troubleshoot this error.
Step 1:
Modify modules/system/system.install
Change following part of code.
// Display the currently active install profile, if the site
// is not running the default install profile.
$profile = drupal_get_profile();
if ($profile != 'standard') {
$info = system_get_info('module', $profile);
$requirements['install_profile'] = array(
'title' => $t('Install profile'),
'value' => $t('%profile_name (%profile-%version)', array(
'%profile_name' => $info['name'],
'%profile' => $profile,
'%version' => $info['version']
)),
'severity' => REQUIREMENT_INFO,
'weight' => -9
);
}
}
Change to:
// Display the currently active install profile, if the site is not running
// the default install profile and the profile is enabled.
$profile = drupal_get_profile();
if ($profile != 'standard') {
$modules = module_list();
if (isset($modules[$profile])) {
$info = system_get_info('module', $profile);
$requirements['install_profile'] = array(
'title' => $t('Install profile'),
'value' => $t('%profile_name (%profile)', array(
'%profile_name' => $info['name'],
'%profile' => $profile,
)),
'severity' => REQUIREMENT_INFO,
'weight' => -9
);
}
}
}

Step 2:
Modify includes/install.inc
After step 1 you might get the error: Notice: Undefined index: distribution_name en drupal_install_profile_distribution_name() (línea 207 de /htdocs/public/drupal7oreilly3/includes/install.inc). You can solve this by making the following changes to includes/install.inc
Two (--) means that this must change with others that are two (++)
-- return $info['distribution_name'];
++ if ( ! array_key_exists('distribution_name', $info)) $info['distribution_name'] = 'Drupal';
++ return $info['distribution_name'];
