无法修复此问题。
有什么线索可以解决这个问题吗？

错误消息抱怨说这/usr/lib/python2.6/site-packages是一个目录，但应该是符号链接。最可能的解释是，您安装的一些软件包不符合当前的 Python 打包策略（额外的软件包放入/usr/lib/python2.6/dist-packages），而是将文件放入/usr/lib/python2.6/site-packages。
运行dpkg -S /usr/lib/python2.6/site-packages以查看哪些软件包不符合当前政策。错误消息会提示您报告这些软件包的错误。
简单的解决办法是删除有问题的软件包。
另一种可能性是，您/usr/lib/python2.6/dist-packages没有通过 deb 包管理器就安装了 中的程序。在这种情况下，请将这些东西移至/usr/local/lib/python2.6/dist-packages。一般来说，您不应该在 中安装或更改任何东西，/usr除非通过调用dpkg它的或更高级的程序（apt-get、aptitude、 Synaptic 等）。例外是/usr/local，您可以在其中执行任何您想做的事情。如果dpkg -S /usr/lib/python2.6/site-packages告诉您没有软件包在该目录下安装任何文件，您只需将目录移动到它应该在的位置：
mv /usr/lib/python2.6/site-packages /usr/local/lib/python2.6/dist-packages
或者如果目标目录已经存在：
mv -i /usr/lib/python2.6/site-packages/* /usr/local/lib/python2.6/dist-packages/
rmdir /usr/lib/python2.6/site-packages
如果您有想要保留安装的旧策略包，我认为您可以使用以下解决方法：
mkdir -p /usr/local/lib/python2.6/dist-packages
mv -i /usr/lib/python2.6/site-packages/* /usr/local/lib/python2.6/dist-packages
rmdir /usr/lib/python2.6/site-packages
ln -s /usr/local/lib/python2.6/dist-packages /usr/lib/python2.6/site-packages
如果mv命令抱怨某些目标已经存在，则需要根据具体情况解决。
如果您确实使用了该解决方法，请做好心理准备，因为如果您在 中安装非 deb python 包/usr/local，则会造成相当大的混乱，因为/usr/local/lib/python2.6/dist-packages将包含一些由 dpkg 管理的文件。另外，我并不完全确定这不会导致任何包管理问题，例如，如果您稍后升级或删除有问题的包，则会出现错误。只有当您准备好稍后进行更多故障排除时，才尝试该解决方法。同样，安全的选择是在升级包之前删除有问题的包python。
