go build runtime/cgo: open /usr/local/go/pkg/linux_amd64/runtime/cgo.a: permission denied

I don't know how this happened, I was using update-golang.sh a while and was always good. Can't remember which golang version I was when this error happened, so I was thinking, give the update a go. The following commands are after installing 1.11.1 already.

I tried different go versions, and I found out the following:

go1.9 ok:

myuser@nb-myuser:~/Projects/go/src/github.com/udhos/update-golang$ sudo RELEASE=1.9 ./update-golang.sh
...
myuser@nb-myuser:~/Projects/go/src/example.io/somegroup/somerepo$ go version
go version go1.9 linux/amd64
myuser@nb-myuser:~/Projects/go/src/example.io/somegroup/somerepo$ go build -i -o bin/srvdef ./cmd/srvdef

go1.10 has the same error:

myuser@nb-myuser:~/Projects/go/src/github.com/udhos/update-golang$ sudo RELEASE=1.10 ./update-golang.sh
...
myuser@nb-myuser:~/Projects/go/src/example.io/somegroup/somerepo$ go version
go version go1.10 linux/amd64
myuser@nb-myuser:~/Projects/go/src/example.io/somegroup/somerepo$ go build -i -o bin/srvdef ./cmd/srvdef
go build runtime/cgo: open /usr/local/go/pkg/linux_amd64/runtime/cgo.a: permission denied
make: *** [build] Error 1

A idea what to look for?

[udhos]

Sorry, I have no idea to suggest.

However I found this issue: golang/go#25138

When I try to use the "net/http" package in a file go build -i prints the following error go build runtime/cgo: open /usr/local/go/pkg/linux_amd64/runtime/cgo.a: permission denied. If I just run go build without -i or if I downgrade to Go 1.9.5 and run the command the error does not appear and everything builds without errors.

It seems the build operation is trying to overwrite the original cgo.a file provided by the Go binary install.

Can you try to build without the -i flag ?

[dionysius]

Wow, good catch! I already looked around but I may have missed that. without -i is indeed working. I think also that -i is obsolete in my case, since the project has vendoring, so no need to download and install anything ("The -i flag installs the packages that are dependencies of the target.")

So then, sorry for bothering. Thank you
