我在 Ubuntu 16.04 中设置无线打印机 HP Officejet 6700 时遇到问题。系统提示缺少 cups。此外，系统提示：
A package manager '[mmcqd/0rpmb] ' appears to be running. Please quit the package manager and press enter to continue (i=ignore, r=retry*, f=force, q=quit) :
我不知道mmcqd/0rpmb是什么。当我进行谷歌搜索时，似乎 HPLIP 出现了某种错误。当我检查 synaptic 时，似乎我已经安装了 cups。

答案1
我刚刚遇到了同样的问题。
经过一些研究却毫无进展后，我试图忽略该过程被标记为包管理器的事实，安装照常完成。
我真的不确定这个过程做了什么，但是它并没有停止运行脚本为依赖项运行的 apt-get install......（或者任何其他自行运行的 apt-get 实例）。
