Xubuntu 13.10 cannot run apt, get error "ERROR: Can't find the archive-keyring"

Asked by Jon Samuels

Every time I try to run anything involving apt-get (install, upgrade, dist-upgrade, etc.) I get the following error:

ERROR: Can't find the archive-keyring
Is the ubuntu-keyring package installed?
dpkg: error processing apt (--configure):
 subprocess installed post-installation script returned error exit status 1
No apport report written because MaxReports is reached already
                                                              Errors were encountered while processing:
 apt
E: Sub-process /usr/bin/dpkg returned an error code (1)

I haven't deleted anything from my keyrings, and this just all of a sudden started with no warning. Not sure what's causing it. Help would be appreciated.

Hi actionparsnip,

The problem's resolved (I didn't see a "close question" button at the time), but here's the output.
