Did all the searches I could think of, so coming here to ask.

I installed 1.8.1 via

tar -C /usr/local -xzf go1.8.1.linux-amd64.tar.gz

Left all my standard stuff alone (been doing go for a while).

Now when I run go install, I get:

go install runtime/internal/atomic: open /usr/local/go/pkg/linux_amd64/runtime/internal/atomic.a: permission denied

I'm running Ubuntu 16.04. My environment:

(addRetries) factomd $ go env
GOARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/paul/go"

Thanks!
