Two packages cannot provide /usr/bin/go. The update-alternatives mechanism is a solution to that (no package provide /usr/bin/go, but they register to update-alternatives that will setup the link). However, it doesn't work well for compilers as it would result in environment-dependent build. The situation is exactly the same with gcc. You install gcc, you get /usr/bin/gcc which is a symlink to gcc-6.

Install golang-1.7-go, not golang-1.7. golang-1.7 is specifically here to also install the documentation. -- Test programs at their boundary values. - The Elements of Programming Style (Kernighan & Plauger)
