My attempt to update my ConTeXtMinimals using ./first-setup.sh failed. The message reported was:

mkiv lua stats : loaded fonts              - none
! LuaTeX error ...mals/tex/texmf-context/tex/context/base/luat-tex.lua:322: attempt to perform arithmetic on local 'total' (a nil value).
<*> ...texmf-context/tex/context/base/cont-nl.tex 
                                                  \dump
?
