每当我安装任何软件/软件包时，我都会得到以下结果。该软件确实安装并正常运行但这不是预期的输出吗？我的系统出了什么问题？

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service acpid restart
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop acpid ; start acpid. The restart(8) utility is also available.

甚至从软件中心：
sudo apt-get update并且关于 unity-tweak-tool 也有一个错误。
注意：尝试安装 Qt Creator 后，这个错误变得越来越长，以前它只有大约四五行，现在却这么长。
