file list:

$ tar -xvf linux-image-unsigned-5.15.0-1004-aws_5.15.0-1004.6_amd64.deb

I am also seeing this.

Looks like this check fails .tar files, it only detects .tar.* files:

go-debian/deb/tarfile.go

Lines 102 to 105 in 9df3f26

	func (e *ArEntry) IsTarfile() bool {
	ext := filepath.Ext(e.Name)
	return filepath.Ext(strings.TrimSuffix(e.Name, ext)) == ".tar"
	}

Will open a PR shortly.
