I have just reflashed my N900 and the first thing i wanna do is to install the CSSU.
So i clicked on install on this page: http://wiki.maemo.org/Community_SSU/
The App. Manager add the repository successfully and then when it comes to install the Community SSU Enabler i get the following error:
unable to install 'community ssu enabler' installation file corrupted

Has anyone faced this before? How to resolve it?

Your input is really appreciated.

Regards
Waddah
