Unable to install theme recommended plugins on Multisite

This is nothing new.
The only problem you have is with the access rights.
Try to work as super admin. All the messages starting with 'Sorry, you are not allowed to access this page.' do have !can_edit_network( $details->site_id ) condition. So you don’t have the access right.

if ( !can_edit_network( $details->site_id ) )
    wp_die( __( 'Sorry, you are not allowed to access this page.' ), 403 );

Work on your access rights.
