@owais do you know if the v0.6.0 tag got force pushed that would cause checksums to fail?

[bogdandrutu]

@owais did a "retag" I think, which is not allowed by golang :(

[owais]

I deleted the tag from github but then tagged the exact same commit thinking that was fine. May be I made a mistake and amended the commit before re-tagging it. We can release 0.6.1 to fix this. I'm not back till Monday. I can make the release then or someone else can do it before then.

Pushed tag v0.6.1, this should be resolved now. CI is building the docker image and soon golang will pick this.
