我正在关注关联在我的 PC 上安装 Qt。
当我输入时sudo apt-get install build-essential g++ libqt4-core libqt4-dev libqt4-gui qt4-doc qt4-designer，出现此错误：
Reading package lists... Done

build-essential is already the newest version (12.1ubuntu2).
g++ is already the newest version (4:5.3.1-1ubuntu1).
Some packages could not be installed. This may mean that you have

我关注了关联寻求帮助，但在输入此命令后sudo apt install libqt4-designer libqt4-opengl libqt4-svg libqtgui4 libqtwebkit4，我应该创建一个脚本文件，但我无法正确理解如何执行此操作。
该命令成功运行sudo apt-get install libqglviewer-dev libqglviewer2但是sudo apt-get install libboost1.48-all-dev没有运行，我收到此错误：
Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libboost1.48-all-dev E: Couldn't find any package by glob 'libboost1.48-all-dev' E: Couldn't find any package by regex 'libboost1.48-all-dev'
的输出apt-cache policy libqtcore4为：
libqtcore4: Installed: 4:4.8.7+dfsg-5ubuntu2 Candidate: 4:4.8.7+dfsg-5ubuntu2 Version table: *** 4:4.8.7+dfsg-5ubuntu2 500 500 http://pk.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status 4:4.8.6+git64-g5dc8b2b+dfsg-3+deb8u1 500 500 http://ftp.ca.debian.org/debian jessie/main amd64 Packages
怎么才能解决这一切呢？

由于你运行的是普通的 Ubuntu 16.04 LTS（赛尼尔），那么你应该删除所有 Debian杰西/etc/apt/sources.list来自您的和文件的提及/etc/apt/sources.list.d/ 。
您可以使用以下方法找到此类文件：
grep -r jessie /etc/apt/sources.list /etc/apt/sources.list.d/*.list
然后通过在开始处添加以下内容注释掉有问题的行#并重试：
sudo apt-get update
sudo apt-get install build-essential g++ libqt4-core libqt4-dev libqt4-gui qt4-doc qt4-designer
