GCR content-type errors

[mithrandi]

I'm seeing a lot of errors logged like this:

ts=2017-12-20T19:50:26.214459657Z caller=warming.go:148 component=warmer err="requesting manifests: getting remote manifest: Get https://gcr.io/v2/kubernetes-helm/tiller/manifests/v2.0.0: http: non-successful response (status=404 body=\"{\
\\"errors\\\":[{\\\"code\\\":\\\"MANIFEST_UNKNOWN\\\",\\\"message\\\":\\\"Manifest with tag 'v2.0.0' has media type 'application/vnd.docker.distribution.manifest.v1+prettyjws', but client accepts 'application/vnd.docker.distribution.manifest.v1+json'.\\\"}]}\")"

This is with Flux 1.1.0 as well as master. The images for the controller(s) in question show as "waiting for cache" forever, presumably due to this error.

Thanks for posting this issue @mithrandi. We were also seeing these log messages, as reported in #838. It was fixed in #851, which made its way to master pretty recently, and will be in the next release (soon!).

(closing as a duplicate of #838, but please do comment here, or file a further issue, if you still have problems that #851 is supposed to fix)

Aha! It looks like I was running the master revision just before that was merged, upgrading does resolve the issue as expected.
