Personally I just received an email informing that there were new updated packages, I found it strange by the date of the same, as it seemed that the update was from the end of last year and after installing I forced the update of Univention.
But now when I checked it again I saw that there were new updates and after applying them, at least FreeNAS started to try again.
I will do the deepest tests now at night, but if everything is correct I already put the post resolved.
