Problem with install

I bought a RaspBerry PI 3.
I want to install a home assistant to Raspberry.
During installation, Raspberry has completed installation with an error.

Raspberry wrote to me:
Warning: sudo() received nonzero return code 1 while executing ‘ln -sd /srv/hass/hass_venv/lib/python3.4/site-packages/libopenzwave-0.3.1-py3.4-linux-armv7l.egg/config’!

And putty wrote to me too:
Server unexpectedly closed network connection

What is wrong?
How to fix this error and continue installing Home assistant?

Make sure that your SD card has enough space.

I have a 32gb sd card and im getting this exact same error
