在装有 Ubuntu 15.04（新创建）的虚拟 Linux 机器上，我即将安装 python-numpy，但是出现了一些错误：
>sudo apt-get install python-numpy
Reading package lists... Done
Building dependency tree
Reading state information... Done
python-numpy is already the newest version.
The following packages were automatically installed and are no longer required:
fonts-texgyre libamd2.3.1 libdsdp-5.8gf libfftw3-double3 libglpk36
libgsl0ldbl preview-latex-style python-cvxopt python-joblib python-patsy
python-simplejson tex-gyre
Use 'apt-get autoremove' to remove them.
The following packages will be upgraded:

Preparing to unpack .../texlive-fonts-extra-doc_2014.20141024-1_all.deb ...
E: Sub-process /usr/bin/dpkg returned an error code (2)
知道如何修复此错误吗？ 无论如何，因为它说 numpy 已安装，这有问题吗？
除了此错误消息之外，我还必须运行命令
sudo dpkg --configure -a
每次我尝试安装某些东西时都会发生这种情况！发生了什么事……？

您的问题与 无关python-numpy。原因是之前安装了texlive。
更改下载服务器
sudo sed -i 's://ch\.://:g' /etc/apt/sources.list
sudo apt-get update
重新安装包
sudo apt-get clean
sudo apt-get install -f
sudo apt-get install --reinstall texlive-fonts-extra-doc
正如你所说，你的虚拟机只有 500 MB RAM
