apt-get -f install. It still failed on me.

It had me stumped at first- I tried clearing the cache and even rebuilding the apt-get config files. Turns out the issue is much simpler; there was no /var/cache/debconf directory!
mkdir /var/cache/debconf, I was able to proceed with the rest of the update. The hint was:
debconf: DbDriver "config": could not open /var/cache/debconf/config.dat. Like any good sysadmin, I decided to see what was in /var/cache/debconf- but as the directory didn't exist.. I created it manually and ran the command again.
