Usually means: you've already uploaded this package/version combination
Ignoring error and continuing, full message from Hackage below:

Error: Upload failed

This version of the package has already been uploaded.

As a matter of policy we do not allow package tarballs to be changed after a release (so we can guarantee stable md5sums etc). The usual recommendation is to upload a new version, and if necessary blacklist the existing one. In extraordinary circumstances, contact the administrators.

@(Stack/Sig/GPG.hs:107:18)
Unable to find gpg2 or gpg executable

(the package was already uploaded, so that error message is warranted - but the GPG error is still there)

Stack version

$ stack --version
Version 1.6.3 x86_64 hpack-0.20.0

Method of installation

brew install stack

@koterpillar Is this still an issue for you? If so, would you try updating to the latest stack with stack upgrade --git (or just stack upgrade after stack 1.8 is released).

[koterpillar]

stack --version              
Version 1.8.0, Git revision 194a674ff9c5c07baf3a748051c9e645fa1f0695 x86_64 hpack-0.29.0

Still happens.

[dbaynard]

So to be clear: the upload works; the error message is irrelevant?

[koterpillar]

Yes, the upload works, but the exit code is 1, which is problematic on CI. I don't have a working signing environment, so I can't test whether the signature is uploaded or not, even when I said not to.

[koterpillar]

I found that --no-signing works in reverse: default is not to sign packages, --no-signing turns signing on. Made #4167 to fix.
