Comment 27 for bug 1029531

I'm not an expert user, so there's probably a simple solution for this. Nonetheless, I'm still having (or I appear to be having) the exact problem described here. I'm trying to upgrade from lucid to precise using the alternate CD (and no network access), but the upgrade keeps failing, saying it "could not calculate the upgrade".

The precise alternate CD I'm using is one I just downloaded within the last few days (it's currently 20-Jan-2013) directly from the Ubuntu site. I would expect it to have all the fixes in precise described above, since they appear to have been released months ago, yet the upgrade still fails.

For what it's worth, I have enabled all of the standard lucid repositories (lucid, lucid-updates, lucid-backports) except for lucid-proposed, run apt-get update numerous times, and it doesn't help a bit.

I will be happy to provide any information I can retrieve for you, or open a separate bug report if necessary (and if I can figure out how), but please do not assume any expertise on my part - I can navigate OK and have no fear of the command line but I have only been using Linux (Ubuntu) regularly for a little over a year. If there are specific log files you need info from, you may need to tell me where they are - I haven't dug that deeply into the inner workings of Linux (yet).
