apt-get trying to fix dependencies of unrelated packages

What is the output of "cat /etc/apt/sources.list"?

Did you preface your "apt-get install nano" command with an "apt-get update" command?

I might have done an update because from the earlier response when trying to obtain nano text editor, I was lead to believe the sources needed to be updated to find new packages.

Nas:~# cat /etc/apt/sources.list
deb http://www.readynas.com/packages 4.1.12/
deb http://archive.debian.org/debian sarge main contrib non-free
Nas:~#

Your APT cache might or might not have "needed" to be updated, but the update could only have helped; it wouldn't have done any harm. You could do it again to make sure that your cache is up to date.

Ah, sorry, I hadn't noticed that you were working with an NV+. Unfortunately, I don't know enough about RAIDiator 4.1.x to give specific advice about sources.

However, libsqlite3-0 version 3.7.4 wasn't released until the end of 2010, almost three years after official support for Sarge was dropped by the Debian project. If such a new version of libsqlite3-0 isn't available from the repositories in your sources.list, it seems odd that it would be required by a nano release available there.

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. My suspicion is that the RN-OS4 devices are now considered EOL, and so disabling this may prevent support traffic and/or prompt people to upgrade. 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.

Since my Linux knowledge is distinctly limited, any idea what this means:

W: GPG error: http://archive.debian.org etch/updates Release: The following signatures were invalid: KEYEXPIRED 1356982504
W: You may want to run apt-get update to correct these problems
