The output file is App-3.0.0-beta2-full.nupkg, (no dot at beta), but the builder trying to upload file App-3.0.0-beta.2-full.nupkg.

[develar]

electron-builder version?

[mbrainiac]

3.20.0

[develar]

How version is specified in your package.json?

[mbrainiac]

My version is 3.0.0-beta.2,
I think the problem is winstaller-fixed removed the dot before creating nupkg, and git uploader use the file with version string from package.json.

[develar]

It is a regression in the last release, fix in progress.

[develar]

Does it work before?

[develar]

   public string SuggestedReleaseFileName {
            get {
                var zp = new ZipPackage(InputPackageFile);
                return String.Format("{0}-{1}-full.nupkg", zp.Id, zp.Version);
            }
        }

winstaller-fixed behaviour correct according to *** Squirrel.Windows *** nuget *** transformation. electron-builder is not aware of such *** transformation.
