Multiple sources are not supported by push command.

Error message

Multiple sources are not supported by push command.

What it means

Thrown by ChocolateyPushCommand.Validate when the resolved --source string (after splitting on ';' and ',') yields more than one source. NuGet push is a single-target operation — it uploads one .nupkg to one feed — so multiple sources are not supported by the underlying push API.

Solutions

1. Provide exactly one source URL for push: 'choco push --source="https://push.chocolatey.org/"'.
2. If you need to push to multiple feeds, run 'choco push' separately for each feed.
3. Check that your defaultPushSource config value does not contain delimiters.

Example fix

// before
choco push --source="https://feed1;https://feed2"
// after
choco push --source="https://feed1"
choco push --source="https://feed2"

// Ensure exactly one source for push
var sources = pushSource.Split(new[] { ';', ',' }, StringSplitOptions.RemoveEmptyEntries);
if (sources.Length > 1)
{
    Console.Error.WriteLine("Push supports only a single source. Use separate calls per feed.");
}

When it happens

Trigger: Passing a --source value containing semicolons or commas that produce multiple segments, e.g. 'choco push --source="source1;source2"' or '--source="feedA,feedB". Any value that splits into 2+ non-empty entries triggers this.

Common situations: User copies a multi-source string (common for 'choco install' which does support multiple sources) and tries to reuse it for push. Or a configuration variable inadvertently contains a delimited list.
