This PR broke the installation of appc/spec for me:

This shouldn't happen. Please provide your go version information

Edit: Just to clarify, I don't think it's a local problem for you, but I suspect the behavior differs between go versions.

$ go version
go version go1.6 linux/amd64

[jonboulle]

It's because of a mismatch in versions between dependencies.
We will move appc/spec to using the vendor/ experiment which should fix
this.

FYI, I am seeing the same issue with go 1.5:

$ gvm install go1.5
Installing go1.5...
 * Compiling...
go1.5 successfully installed!
$ gvm use go1.5
Now using version go1.5
$ gvm pkgset create test
$ gvm pkgset use test
Now using version go1.5@test
$ go get github.com/appc/spec/schema
# github.com/appc/spec/schema/types

@elemoine The problem is that k8s introduced a breaking change in kubernetes/kubernetes@b2a01d4 and your go get is retrieving that version of the package. We do vendor in the repository but go get doesn't understand that because we haven't moved to the vendor experiment (yet). If you check out the repository and build using ./build it should work fine.

I am quite new to Go but it seems to me that all packages that depend on appc/spec/schema are broken by this.

I initially found the problem while installing Snap (intelsdi-x/snap#953). But here's another example:

$ go get k8s.io/kubernetes/pkg/kubelet
# github.com/appc/spec/schema/types
/home/elemoine/.gvm/pkgsets/go1.5/test/src/github.com/appc/spec/schema/types/isolator_resources.go:158: cannot use req (type resource.Quantity) as type *resource.Quantity in field value
/home/elemoine/.gvm/pkgsets/go1.5/test/src/github.com/appc/spec/schema/types/isolator_resources.go:159: cannot use lim (type resource.Quantity) as type *resource.Quantity in field value
/home/elemoine/.gvm/pkgsets/go1.5/test/src/github.com/appc/spec/schema/types/isolator_resources.go:212: cannot use req (type resource.Quantity) as type *resource.Quantity in field value
/home/elemoine/.gvm/pkgsets/go1.5/test/src/github.com/appc/spec/schema/types/isolator_resources.go:213: cannot use lim (type resource.Quantity) as type *resource.Quantity in field value

Sounds like a big issue to me. Not something I should work-around by checking out the repository and do ./build. No?

[jonboulle]

@elemoine can you try this again now?

[elemoine]

It works. Thanks a lot!
