Comment 51 for bug 116193

I also had the latest tzdata package getting the following error after I changed the /etc/timezone file from America/North_Dakota/Center to America/Chicago and then running the command sudo dpkg --configure tzdata

    Setting up tzdata (2007h-0ubuntu0.7.10) ...
    dpkg: error processing tzdata (--configure):
    subprocess post-installation script returned error exit status 10
    Errors were encountered while processing:
     tzdata

But I was able to get it work after also changing the time zone in the Clock applet contained in the upper panel. That is, I did the following:

    Right mouse clicked the date/time on this panel

    Clicked the Adjust Date & Time option

    Changed Time Zone in the Time and Date Settings Window to America/Chicago
    from America/North_Dakota/Center

    Ran the command: sudo dpkg --configure tzdata

I don't know if this makes any difference, but I have my clock set to Local time not UTC.
