您的系统上可能安装了另一个推荐或建议jackd2.你可以用aptitude why jackd2它来找出答案。

就我而言，它是blender通过另一个依赖项的包：

$ aptitude why jackd2                                                                                      
i   blender          Depends  libjack-jackd2-0 (>= 1.9.10+20150825) | libjack-0.125
i A libjack-jackd2-0 Suggests jackd2 (= 1.9.12~dfsg-2+b1)

并且您的 apt 可能配置为将推荐和建议视为依赖项，其设置称为APT::Autoremove::RecommendsImportant和APT::Autoremove::SuggestsImportant。

我建议保留第一个设置，但您可以安全地禁用建议设置（但它仍然可能会卸载您想要保留的一些软件包，在这种情况下取​​消将它们标记为自动安装）。

要禁用处理建议和依赖于自动删除的设置：

sudo apt-get autoremove -o APT::Autoremove::SuggestsImportant=0
