A recent convert to QGIS, I have versions 2.8.5 and 2.12.2 installed on my PC. The plugin Manager tells me I have v2,10.3 of the Processing plugin installed in the plugin folder of my local drive and v 2.12.2 is available in the official repository. When I try to upgrade I get the following error:
Plugin installation failed: failed to unzip the plugin package. Probably it's broken or missing ftom the repository. You may also want to make sure that you have write permission to the plugin directory: C:/Users…./.qgis/python/plugins
I have been able to successfully install other plugins and have manually tried copying the processing folder from a colleagues successful update into the plugin folder but the error persists.
Any idea what I'm doing wrong?

The processing plugin behaves a bit different from others.
It is now a core plugin, installed to
C:\programs\<QGIS version>\apps\qgis\python\plugins, whereas plugins from the plugin manager get installed toC:\Users\<user name>\.qgis2\python\plugins. Additionally, there is a folder namedC:\Users\<user name>\.qgis2\processingcreated even for the core version.While the first is installed newly with every QGIS version, the plugin manager installs one for all.
I suggest to remove the second, and use the core function with the different versions of QGIS you have.
