E: tzdata: subprocess installed post-installation script returned error exit status 1

I got the above error while attempting to install updates on a Linux Mint system. This thread provided a few possible solutions, none of which worked for me (though I was glad I discovered the grub » recovery mode » repair broken packages option, which might come in handy in the future). Digging a bit, I ran:

dpkg --configure tzdata

and noticed,

debconf: DbDriver "config": could not open /var/cache/debconf/config.dat

There was no /var/cache/debconf/ directory and, as indicated here, simply creating it would provide a fix. So a simple:

sudo mkdir /var/cache/debconf

… and I was good to go!
