Can be fixed by running:

sudo apt-get install ubuntu-extras-keyring

As far as I can tell it was only omitted from the 10.10 RC builds. The release versions seem fine in my limited experience so far.

I already had ubuntu-extras-keyring installed, but was still getting this error. Manually reinstalling fixed it:

sudo apt-get --reinstall install ubuntu-extras-keyring
