Why cannot I install this module? I installed Drupal 8 distribution in Acquia Drupal. I am trying to install the Panels module after downloading the archive file from drupal.org.

I am not able to select the Panels module to install it.
Is there any other additional module to install, apart from the Layout Discovery module?
If you go through the panels module README file. It clearly says the below:

dependencies:
  - ctools
  - layout_discovery
  - drupal:system (&gt;= 8.3.x)
test_dependencies:
  - page_manager


Make sure you have the above modules pre-installed for Panels.
