Don't think so.  I believe it means that the alt or live CD you used to install with is not in the CD_ROM drive and there is an entry in your sources.list file for that CD-ROM.  As suggested before, if you remove or comment out that CD-ROM entry in your sources.list file the error message will go away.  Try it and see for yourself and note that there may be more than one CD-ROM entry in your sources.list file.  Be sure to rm or comment out all of them for the error to go away.
