I have been troubleshooting an 'Update Error!' for a few days now with Sparkle and have made little progress. I modeled my appcast after a working sample as closely as I could but I couldn't get it to work. Finally, I just decided to use the sample appcast in my app to test:
http://sparkle-project.org/files/sparkletestcast.xml
When I put that as my SUFeedURL, voila, it works. So I copied and pasted the contents of that XML to the file on my server and it doesn't work. Looking over the diff closer, the only material difference is the sparkle:dsaSignature, which I don't have a valid value for.
Reading over the documentation, however, I got the impression that I only needed to deal with the dsaSignature stuff if I am not signing the app myself with my certificate. When I am deploying the build of this app, I am exporting it from Xcode and signing it with my dev identity, and then zipping it up and putting it on the server.
Do I need the sparkle:dsaSignature field in my appcast if I am signing the app myself? I can't figure out why this isn't working.
