Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information. At a minimum, we need: 1. the specific steps or actions you took that caused you to encounter the problem, 2. the behavior you expected, and 3. the behavior you actually encountered (in as much detail as possible). Please also add all the files from '/var/lib/ufw', '/etc/ufw' and '/etc/default/ufw' to this bug as separate attachments and give the version of ufw as seen with 'ufw --version'. Thanks in advance.

I use "sudo ufw status" to view firewall state info, the command line didn't return firewall state info, but the following error happened.

I cannot reproduce this. I copied all your files into place and 'ufw status' works fine. Can you give steps to produce the problem, starting with a fresh install of ufw? That, do:
$ sudo dpkg --purge ufw
$ sudo rm -rf /var/lib/ufw /etc/ufw
$ sudo apt-get install ufw

If you are able to reproduce it, can you also state your locale?
