I use this command to update all my GOPATH:
go get -v -d -u .../ (or replace ".../" by "all")
It worked with Go 1.5 (and I don't remember to see any error with Go 1.6 beta/rc)

With Go 1.6, it prints this at the end:

Appears to have been introduced by https://golang.org/cl/18978.

https://golang.org/cl/18978 introduced changes that fixed the errors appearing earlier then these, so it did not break anything.
The issue here is that go get -u all is trying to update commands too. The commands cache was not clearing and their packages were not rebuilt using new packages cache for imports. That led to duplicated standard packages in the packageList and that's why we were getting these errors. I've added command cache clearing and test for that into https://golang.org/cl/19899

cmd/go: clear cmd cache to avoid duplicate loads errors
286a9c3 
go get -u all command updates all packages including standard
commands. We need to get commands evicted from their cache to
avoid loading old versions of the packages evicted from the
packages cache.

Fixes #14444
