Please provide any additional information below.

I reported a similar problem before. Even though the all.bash failed, I was
able to compile and run hello,go and echo.go programs. Is the install
successful or not?

Comment 1 by rydmen:

Hi, teluguloshi. I am completely new to Go, but from what I can see the code is
installed once this error occurs. As a workaround until smart people take a look at
this, try adding net to NOTEST in src/pkg/Makefile. This allowed the tests I was
running to complete normally.

Comment 3 by sydehh:

same issue on ubuntu. It appears it's only that test failing and it's still built fine.
added net to notest for now, thanks rydmen.
