我有一个 Debian 6 VMWare 虚拟机，主要通过 SSH 使用（但偶尔通过 GUI）。
每隔几分钟，我的终端就会打印以下消息：
CUPS config timestamp change detected but old config retrieved via interface!
有一段时间，我忽略了它。然后，我卸载了 CUPS：
$ sudo apt-get remove cups
$ sudo apt-get autoremove
并重新启动。我仍然收到消息。
我到底怎样才能阻止它呢？我永远不会想用这台机器打印。
答案1
a) 移除杯子并不会真正移除 CUPS。
b) 你可能想使用apt-get purge而不是删除。
您至少要清除这批货物。您可以使用通配符或正则表达式来完成此操作。
apt-get purge '^cups'
似乎删除所有以 cups 开头的包，但实际上我们想要包含 cups 的所有文件。请正则表达式专家来救援。 :-) 请参阅apt-get purge '^cups'下面的输出。
（更新：根据 Paul 下面的评论，GNOME 显然坚持安装一些 CUP 库，所以我建议他删除前端的东西，所以事实上也许他真的想要apt-get purge '^cups'）。
$ dpkg -l | grep cups

答案2
啊——事实证明我认为这实际上是一个 VMWare 问题。我在 VMWare 虚拟机的设置中禁用了打印机，你瞧，问题（似乎已经）消失了。 VMWare 一定一直在尝试让打印工作。
