Failing to update a PPA but which one?

[DJ_Peng]

I've been noticing an odd error when I try to run a sudo apt-get update in the last few days. The gist of the error is shown in this output from the end of the update process:

Hit http://ppa.launchpad.net karmic/main Packages
Err http://ppa.launchpad.net karmic/main Packages
404 Not Found
Hit http://ppa.launchpad.net jaunty/main Packages
Hit http://ppa.launchpad.net jaunty/main Sources
Fetched 8,101B in 3s (2,588B/s)
W: Failed to fetch http://ppa.launchpad.net//ppa/ubuntu...86/Packages.gz 404 Not Found

E: Some index files failed to download, they have been ignored, or old ones used instead.

I have quite a few PPA's that I use, and I notice the extra slash before the second "ppa" right off, but I have no idea which PPA is giving me trouble. I've gone through my entire sources list and tried to verify that the source data is correct but I still get the error. Is there a way to identify specifically which PPA is being troublesome?

Edit /etc/apt/sources.list and comment out all the ppa's. Do a sudo apt-get update and you should not get any errors. Now uncomment the ppa's one at a time, doing the update after each change. When you get the error, the problem is the last one you changed.

I was afraid that was going to be the best solution. With the number of PPA's I use that method is a pain in the rear. I was hoping there was a way to get a verbose output with the sources being checked as it runs.
