During an upgrade from Ubuntu 12.04 to 12.10 dictionaries-common post-installation failed with these lines in apt-term.log (full log attached):

Running "sudo dpkg --configure --pending" results in the same error.

I ran /usr/share/debconf/fix_db.pl which made the following changes:
david@dreamon:/usr/share/debconf$ diff -u /var/cache/debconf/config.dat{-old,} | grep ^[+-]Name
+Name: popularity-contest/participate
+Name: popularity-contest/submiturls
+Name: shared/packages-wordlist
+Name: wamerican/languages
+Name: wbritish/languages
david@dreamon:/usr/share/debconf$ diff -u /var/cache/debconf/templates.dat{-old,} | grep ^[+-]Name
+Name: popularity-contest/participate
+Name: popularity-contest/submiturls
+Name: shared/packages-wordlist
+Name: wamerican/languages
+Name: wbritish/languages

And the error is fixed now. I think this is a dupe of bug 873551 except that was an upgrade from Natty to Oneirc (11.04 to 11.10). Should I mark this as a duplicate?
