Trisquel Sugar installer doesn't work properly

I installed Trisquel Sugar version but the graphical installer have some issues like on the step to select the wifi it keeps loading when the popup after select to insert the password, also on the 3er step keeps loading and after 15min or more it moved to the next step, the same happened on the step to select the country, in my firsts attempts when I tried to close or cancel the interface froze it, I finally installed but waiting a long time on those steps.
