What does it mean by "Wrong domain"? How do I go about correcting this?

Thank you,
David

No answers?

did you try this?
Re: My Application Manager flat out doesn't work

before Googling for it, my advice would have been to open the catalogs, copy the content of all the fields for each repository and (except maybe Nokia system software) delete them all & then add them again, one by one.

ps: ever thought switching over to FApMan ?

misterc,
Thank you. I did google with various search terms but the results were not identical to the symptoms I'm experiencing. I'm still getting updates (I've been through 4 or so Modrana updates since this "problem" began). I was not sure if the update results I posted were normal or not (ModRana still updating). I'm guessing they are not normal.
I'll re-set all of the update fields as you suggested (that's pretty safe to do).

Thanks again,
David

i got a, well not exactly the same but somewhat same error. I got :
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY ADB4438160A655EF

it says you may want to run apt-get update to correct the problem but the result is the same everytime i do. =/

I got exactly same output when running apt-get update. Disabling all repos and enabling them again didn't work out.

I disabled all of the repos and entered them again as new. This resulted in constant update reminders for "System Info Widget", "Timerjinni", "Modrana" and "Tuner". I put those updates through and 15 minutes later I saw the update icon in my taskbar. Clicked and found it was the same 4 programs. I allowed them to be updated and an hour later the update icon returned... same 4 programs... This continued until I deleted the Repo entries I created to replace all the others.
I learned the hard way that some symptoms are not related to the install of a new program or update... I did updated ModRana just before this began and I'm not sure whether or not it's related. I've had (not including the 5 repeats) 4 ModRana updates in the last 5 weeks and the second was updated about the time this problem began. I'm going to uninstall it, battery out restart and try the update interface again. If it fixes it I'll let people know here (and the writer of ModRana). I'll re-install ModRana afterward.

David

No, deleting ModRana did not fix. I'll re-install it.
It may be time to re-flash my N900.

So where is this GPG Public Key (I understand it's GNU) If the problem with it is within my device how to I gain a new key? If others are having the same problem is the key bad on the repo server side? I strongly suspect that the problem is device side, but how to repair it is outside of my realm of knowledge.
Do I need sudo gainroot to use this command?: gpg --import public.key
Do I need to be in a specific directory?
Thanks to anyone who can help!

Forget the gpg issue, it is someone else's problem and shouldn't affect you, in my experience. The other errors you got are the important ones.
