It is not a general texlive problem. It works fine for me and for
lots of other people. 

I don't know your OS but  /etc/texmf/web2c/fmtutil.cnf sounds like a
local, older fmtutil.cnf, and adapting it to the new luahbtex engine
is the right thing to do (or perhaps you should check, why you have
this fmtutil.cnf and if it is still needed at all).
