Upgraded from 7.41 to 7.42 = Error Messages

Hello,

I just upgraded from 7.41 to 7.42.

I do not use Drupal 100% and I am not really an expert.

I got these error messages:
Notice: Undefined index: distribution_name in drupal_install_profile_distribution_name() (line 207 of /myuser/mypath/includes/install.inc).
Notice: Undefined index: name in system_requirements() (line 34 of /myuser/mypath/modules/system/system.install).
Notice: Undefined index: version in system_requirements() (line 36 of /myuser/mypath/modules/system/system.install).

I have no idea how to fix these.

I found this post: https://www.drupal.org/node/1116340
But I do not think it applies.

please help.
thanks.
