Fail to update to airtime 2.2

I currently use airtime 2.1.3 but when I try to update to 2.2 I get the fallowing error: "Existing smb.conf does not have a [netlogon] share, but you are configuring a DC"

I have checked my current install with "invoke-rc.d airtime-playout statu" and I get "Your installation of Airtime looks OK!"

Could please tell me how to fix it or why is this happening. (See complet install log attached)

Thank you !
