Hello everybody!
Thank you Alessio, @mabeleira, @WillZen!
My point of view based on NS 6.7 (final).
Is not the proper order. Just for grouping.
NethServer 6.7 (final) installed from scratch as AiO - VM in VirtualBox.
All updates.
I have installed everything from Software center, without Languages.
It is possible that I have missed something in UI_6.7_final.xlsx.
