当我尝试使用 apt-get 安装任何东西时，出现以下错误：
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 60, in <module>
sp = SoftwareProperties()
File "/usr/lib/python2.6/dist-packages/softwareproperties/SoftwareProperties.py", line 90, in __init__
self.reload_sourceslist()
File "/usr/lib/python2.6/dist-packages/softwareproperties/SoftwareProperties.py", line 538, in reload_sourceslist
self.distro.get_sources(self.sourceslist)

raise NoDistroTemplateException("Error: could not find a "
aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template
知道这意味着什么以及如何解决吗？
