Hello

The samba package install problem do not occur anymore.
But since upgrade to 16.04 each access to a samba share need a authentication and scheduled tasks fails. (After upgrade from 12.04 to 14.04 the same problem occurred for several month before been solved by a update.)
I removed the machine from the domain an tried to join again. The join fail.


Below copy of some commands and the terminal outputs :
