I have installed a number of packages with much pain. (I've a slow internet connection)

Now I want to reinstall Ubuntu (I use 10.10), but I don't want to download all the packages again. I have burned a disk containing all these packages (with APTonCD, which I think don't solve dependency headache.)

Is there any easy way to override manual dependency solving? (Even though there is, I would like to know how to do it manually.)

Can I back up system configuration?

Thank you.

I've cleaned up your question as best as I could, but I'm not entirely sure what you're asking for in your 3rd paragraph. apt normally handles dependency resolution, but there should be options for allow installation of packages in a broken state. Or else you could use dpkg itself. – afrazier May 23 '11 at 17:50

Let me preface with this:

  • my Linux skills are rusty maybe out of date.
  • I used to maintain 4 Ubuntu machines at home with a local package mirror.
  • I have not tested these possibilities.

Ubuntu, does have a package to keeping a CD up-to-date. Ubuntu and Debian can build install discs from a package mirror using JigDo

I would suggest Jigdo as your first option. I take it that bandwidth is at a premium by you.
Jigdo will build an updated install ISO given one or more package sources. One of these sources can be an existing install CD/DVD. I believe that CD should be an existing install CD/DVD, but it wouldn't hurt to try pointing it to your APTonCD ISO you made.
