+ERROR: No matching distribution found for ansible==7.6.0 (from -r requirements.txt (line 1))

+It means that the version of Python you are running is not compatible with the version of Ansible that Kubespray supports.
+If the latest version supported according to pip is 6.7.0 it means you are running Python 3.8 or lower while you need at least Python 3.9 (see the table below).

 ### Ansible Python Compatibility
 
 Based on the table below and the available python version for your ansible host you should choose the appropriate ansible version to use with kubespray.
 
 | Ansible Version | Python Version |
 |-----------------|----------------|
-| 2.11            | 2.7,3.5-3.9    |
