apt-get trying to fix dependencies of unrelated packages

For anyone else attempting this on an x86 Legacy NAS, be aware that NETGEAR have deemed it necessary to comment out the second repository so the only "active" sources are now those provided by NETGEAR, which will probably foil any attempts at installing anything they don't want you to. .... Removing the "#" at the beginning of the second line in the sources list on FW4.2.24 will reverse this change.

And if you're brave enough to do that, you might want to add a couple more sources, too. Here's the sources.list I use for my Pro Pioneer and Ultra 2 Plus running 4.2.24:

deb http://www.readynas.com/packages 4.2.24/
deb http://archive.debian.org/debian-security etch/updates main contrib non-free
deb http://archive.debian.org/backports.org etch-backports main contrib non-free
deb http://archive.debian.org/debian etch main contrib non-free

Using those sources, I've had no trouble with either device after performing an "apt-get update" followed by "apt-get upgrade". Your experience may differ, of course; as always, it is recommended to backup before upgrading.
