What or where is the wrong?

Are you running an installed version of LinuxCNC or one you compiled yourself?

That does not really answer the question. I'm sure Andy does not use MX Linux and neither do I.
Do those instructions require you to use make or did you use synaptic or apt?
Also errors should have a line number reported. check which line it fails on and what is on that line.

I installed it with synaptic.
The error message is in the line:
Addf downdraft servo thread

Did you use sudo when you used halcompile. you need root access to write to the folder.

This is the result of halcompile:

compiling realtime downdraft.c
Linking downdraft.so
cp downdraft.so /usr/lib/linuxcnc/modules/

Is this the right place to put the file?

sudo halcompile --install 
allways works for me. 
Perhaps try the comp and wcomp components Andy linked to as they are part of the core.

Yes, it seems to have gone to the right place.

The function name is probably downdraft.0

(and it might be simpler to use one of the built-in modules, terse[1] documentation aside.)

[1] Terse to a fault, I agree

Actually, I think my hal example uses names=ddraft
and has a typo
try
addf ddraft servo-thread
