New in linux trying install

In the web Lotus: Install and setup ( there is a few steps, i believe i make 1,2,3 and 4 correctly, (4th not sure, i made the two options)

In 5th stept, it says: Build and install lotus:
make clean all

In this step, last 3 lines i get are:

go build -ldflags="" -o lotus ./cmd/lotus

bash: go: orden no encontrada (order not found in english). i use spanish

make: *** [Makefile: 68: lotus] Error 127

and, if i try to continue and i execute next line in instructions (sudo make install) i get the following lines:

bash: go: orden no encontrada (order not found in english)
expr: syntax error: unexpected argument <<14>>
install -C ./lotus/user/local/bin/lotus
install: no se puede efectuar ‘stat’ sobre ‘./lotus’: No existe el archivo o el directorio
(in english install: cant be done ‘stat’ over ‘./lotus’: File or directory doesn`t exists)
make: *** [Makefile:104: install-daemon] Error 1

I dont know where i failed to get this errors, and how can i solve them.
