there is no channel with the name %s associated with the buc

Error message

there is no channel with the name %s associated with the bucket %s

What it means

GetChannel in service_channel.go is the current replacement for the deprecated channel lookup; when PackerServiceGetChannel succeeds but resp.Payload.Channel is nil, the requested channel name is not associated with the bucket and this error is raised. Used when resolving which iteration a channel (e.g. a release channel) points to.

Solutions

Check the HCP Packer console that the channel exists for the bucket and copy the exact name.
Create the channel in the registry if it is missing.
Correct the bucket_name/channel configuration in the template or data source.
Consider enabling auto-configure of channels if supported by the datasource.

Example fix

// before
channel = "stable"   // channel does not exist on bucket
// after
channel = "production" // existing channel, verified in HCP console

Defensive patterns

Strategy: validation

Validate before calling

if !channelExists(bucketName, channelName) { // check via HCP console/API
    return fmt.Errorf("channel %q missing on bucket %q; create it or fix the name", channelName, bucketName)
}

Try / catch

ch, err := client.GetChannel(ctx, channelName, bucketName)
if err != nil {
    if strings.Contains(err.Error(), "there is no channel") {
        return fmt.Errorf("channel %q not found on bucket %q", channelName, bucketName)
    }
    return err
}

Prevention

Verify channel names in the HCP Packer console before configuring templates.
Create channels for every bucket referenced by packer datasources.
Keep bucket and channel naming consistent across pipelines.

When it happens

Trigger: PackerServiceGetChannel returns success with resp.Payload.Channel == nil for channelName on bucketName — the channel simply does not exist for that bucket.

Common situations: Config referencing a channel never created; channel deleted from the registry; wrong bucket name in template configuration; case sensitivity mismatch in channel names.
