Issues installing with apt-get 404 not found??

Is it would seem that the saucy packages no longer exist. How can I update/upgrade without wiping and reinstalling from scratch?

Hi...

The repository may have been shut down for this version of Ubuntu. For "libboost-signals-dev," you can download the .deb file for this package here for 32 bit or here for 64 bit. Once downloaded, just navigate to to where they are located and double click on the file to install it.

You may need to install the main libboost packages (if you don't already have them) or other dependencies. If so and you can't find them, post back with the packages needed and I or another member can try to help you locate them.

Regards...
