Please correct the at_core.info.yml file

Problem/Motivation

Version 7.1.1 still contains an old AT bug that prevents both the installation of at_core with Drush and the activation of the sub-theme created with AT Theme Generator.

In fact, if you try to install at_core via Drush, you get the error message “Unable to install modules at_core due to missing modules at_core.”, while if you try to enable the sub-theme created, you get the message “This theme requires the at_core base theme to function correctly.”

This is all due to incorrect naming in the at_core.info.yml file

base theme: stable
.....
......
core_version_requirement: ^10 || ^11
package: adaptivetheme
hidden: true
features:
dependencies:
  - stable:stable

which, in order to function correctly and be installed, must be

base theme: stable9
.....
......
core_version_requirement: ^10 || ^11
package: adaptivetheme
hidden: true
features:
dependencies:
  - stable9:stable9
