tentei fazer a instalção do samba 4 mas está dando erro. Fiz pela console (apt-get) e agora tentei pelo webmin.
O erro é o seguinte:

já removi apt-get remove samba e também com samba4
já fiz apt-get check
já fiz apt-get clean
já fiz apt-get update
já fiz apt-get upgrade
e outro comandos.
Podem me ajudar?
