The good news is you are now downloading the Google tools, so you got past the previous error.

"~" is a Linux shell symbol for user's home directory , see any Linux tutorial. 
From some directory other that your home directory try `ls ~'

I don't know anything about the error you get, it is some system or network issue there.

I can click on the link in your post and download the file - so the link is good.
