Possibly the dumbest question..

[year0]

OK, I've installed minetest via the ubuntu software depostiory (I'm on ubuntu 14.04 32 bit)

And I can start a game, and it works - however I can't for the life of me install any mobs.. I've downloaded a few from this forum, but on starting a new world I get dependancy errors (mobs and mobs_monsters)..
I've looked for those packs on here, & i even did a re-install, but I'm still doing something wrong..
Thanks, and sorry if this is a dumb question, I've just found minetest

best, post as we need the log messages inside code block

but anyway, read then, most answers are included, as depends on [Mod]xxx, so missing that and will not start without it.

Go here: viewtopic.php?t=9917

and get download "Mobs Redo", "Mobs Animals" and "Mobs Monsters", unpack into your .minetest/mobs folder and enable for your world before entering.
