Sorry to bump this thread but it seems the closest to the problem I am having. For some time I have been getting "BADSIG E40DC434616730BD maemo.org Extras repositories (Fremantle Extras) <repositories@maemo.org>"

Googling for this error it seems that noone else has seen it for years, and certainly not since CSSU.

I've tried the usual replacing the key in the keyring but makes no difference. I'm starting to suspect I have the wrong repos in my source list.

Can someone with a working CSSU/testing installation please paste the contents of their /etc/apt/sources.d/hildon-application-manager.list

Thanks!
