[Bug 1306851] Re: Xubuntu 13.10 cannot run apt, get error "ERROR: Can't find the archive-keyring"

[Jon Samuels]

Fixed by doing the following:

- sudo mv /usr/share/keyrings/save/ubuntu-archive-keyring.gpg.backup /usr/share/keyrings/ubuntu-archive-keyring.gpg
- sudo apt-get install --reinstall ubuntu-keyring

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

Status in “apt” package in Ubuntu:
  Invalid

Bug description:
  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.
