I gave it many tries and only when manually adding your recommended 
firewall-cmd command, I was able to go one step further in the run.

Next issue is there :

So here is the time I have to admit I'm trying to run all this on a 
*very* humble machine, with only 4Gb of RAM, that may sound ridiculous 
but I am prepared to wait for days between each command return and mouse 
click, as long as everything is doing its job (slowly).

Not being able to allocate memory is blocking me from even testing Lago.

Wouldn't be somewhere I could tweak some limits?
