Debconf says I have no active swap space
I've seen this the last several times I reinstalled my distro, and have meant to ask about it. When I upgrade Debconf to the latest version, it reports I have no valid swap space. I didn't know why it would say that, because of course I have one--about 20 GB. Then I finally bothered to click Help, and found: "The swap file that was found in uswsusp's configuration file is not active." I guess that means uswsusp doesn't know the location of my swap partition? Where is uswsusp?--I don't know where to look for it.
This has not seemed to affect my system, except that the help dialog says I will be unable to use software suspend. I guess that means if I fix it, I will probably be able to make the system hibernate instead of having to shut down; it's been years since I could get it to hibernate.
