一张纸条：这个问题可能与如何在软件中心取消安装？但那里列出的解决方案对我没有用。
问题：
我正在尝试从 Ubuntu 软件中心终止软件安装。我尝试matlab-support 0.0.17从软件中心安装：
此软件包不提供 MATLAB。相反，它配置现有的 MATLAB 安装，以便更舒适地集成到 Debian 安装中。
然而， 我的系统上没有安装 MATLAB并意外尝试下载matlab-support 0.0.17。结果，我面临以下问题：
每当我打开 Ubuntu 软件中心时，我都会注意到有一个进程一直在运行。它显示 matlab-support 0.0.17 正在安装...
我寻找一种方法来终止安装进步标签来获得这个：
一旦到达那里，我看不到取消选择或终止该过程的方法。

答案1
首先我们必须找到阻塞进程：
sudo fuser -v /var/cache/debconf/config.dat
示例输出
USER PID ACCESS COMMAND
/var/cache/debconf/config.dat:
root 11060 F.... dpkg-preconfig
和
ps xa | grep apt
示例输出
24743 ? S 0:00 /usr/bin/python /usr/share/apt-xapian-index/update-apt-xapian-index-dbus
终止两个进程
sudo kill -9 11060
sudo kill -9 24743
您的问题就解决了。
尚未matlab-support安装，因为您已使用此命令识别
dpkg -l | grep matlab
答案2
我在使用 gparted 时遇到了完全相同的问题。但是，我在“如何在软件中心取消安装？”中看到了这个问题：
pkill -15 dpkg
它对我有用，如果您尚未解决问题，我希望它对您也有用。
