package python-ufw 0.34~rc-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Long story short, author uses python2.7, and my machine uses python3.3 as python. Module ConfigParser has been changed to configparser in python3. Please accomodate your software for new python versions

Thank you for using Ubuntu and filing a bug.

I'm not sure what you mean by "Long story short, author uses python2.7, and my machine uses python3.3 as python." ufw is tested to work with python 2.6-2.7 and python 3.1+ (in fact it defaults to python3 in later Ubuntu releases and python-ufw (the package that failed) is only provided for other python2 apps that use ufw). Specifically, src/applications.py has:

if sys.version_info[0] < 3:
    import ConfigParser
else:
    import configparser

You later say that "my machine uses python3.3 as python". Do you mean that you changed the symlink for /usr/bin/python to point to /usr/bin/python3.3 instead of /usr/bin/python2.7? If so, this is not the recommendation from PEP-0394 and is unsupported in Ubuntu and Debian and I would expect many other python2 applications to fail. This has been discussed in various places:
https://mail.python.org/pipermail/python-dev/2013-July/127529.html
https://wiki.ubuntu.com/Python/3
http://legacy.python.org/dev/peps/pep-0394/

My mistake, close this bug. I didn't know that 2.7 is still default python for ubuntu, i symbolic linked python3.3 to python, and was getting bugs
