QGIS无法在Wily15.10上安装Python :损坏的路径/依赖项

Question

当我尝试运行QGIS时，在启动时会发现以下错误：

An error occured during execution of following code:
import pyplugin_installer


Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 572, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
ImportError: No module named pyplugin_installer


Python version:
2.7.10 (default, Oct 14 2015, 16:09:02) 
[GCC 5.2.1 20151010]

QGIS version:
2.12.1-Lyon 'Lyon', exported

Python path:
['/usr/share/qgis/python', u'/home/jesse/.qgis2/python', u'/home/jesse/.qgis2/python/plugins', '/usr/share/qgis/python/plugins', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/home/jesse/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PILcompat', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/wx-3.0-gtk2', u'/home/jesse/.qgis2//python']

此后，QGIS启动。然后，当我尝试打开Python控制台或插件菜单时，会收到类似的错误消息。

我尝试过apt-get purge qgis，然后用apt-get install qgis -f重新安装它。但是，在试图清除/安装时，我会收到以下错误消息：

显然，这个问题似乎与Python有关，但我不知道如何诊断这里的错误。有没有人对如何解决这一问题有任何想法，或者对其他地方有什么想法来寻找关于正在发生的事情的线索？谢谢。

我也有同样的问题，但现在又起作用了。

我在今天安装的这个更新中修正了这个问题：
