As of 2/25, Fennec’s build system has changed to incorporate datetime to filenames in .deb files. For anyone that’s been automatically updating Fennec nightly builds on their Nokia Maemo devices, will not continue to receive those updates unless you uninstall Fennec and then re-install it back onto the device. The reason for this change is to better work with Nokia’s application manager update service in the future and remove any potential headaches that might come about with changing versions.
If you need any help setting up your device again, just check out my blog post written back on 1/18 that offers a step-by-step guide to do so.
