Error no space left

I followed the post:
To do this, I prepared a virtual machine with Linux 18.04 server operating system, a 512GB hard drive, 16GB of ram and 8 cpu. I tried to import the map of Europe, but when I run the command of step 5 “osm2pgsql …” I get this error:
Ubuntu 2.1
This is the situation of the HD:
Ubuntu 2.2
Now I’m not a Linux expert but it seems to me that there is space on the HD.
Can any expert user help me?
