Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Looks like it failed attempting to modify something for the user 'JG' which doesn't exist.

usermod: user 'JG' does not exist
dpkg: error processing package kismet (--configure):
 subprocess installed post-installation script returned error exit status 6

Hi,

If you see in the log there is this message:
user 'JG' does not exist

Could you please specify a valid username when it requests for the users in the kismet group?
An easy solution is to uninstall and install kismet again.

This issue has been fixed in the newest version of kismet.
It is a duplicate of a previously reported bug and I'm marking it as such.
Please comment here if you need additional help

Kindest regards,
Nick
