Until ArcoLinux 18.11 Samba was installed on the iso.
The ArcoLinux 18.12 edition and later will no longer have samba and samba related software.

Since we had issues with Samba end of November we investigated Samba and decided not to include it anymore on the iso.

If you do want samba in the future then we have 2 scripts on any of the ArcoLinuxD githubs to install it.

Scripts 140 and 150 will take care of that.

Run these two scripts and you will have samba back.

November 2018 we need to keep an eye out for the update of winbind.
