Hi Jamie.

Is with 'IPV6=no' in /etc/default/ufw

The error is with the commands "ufw enable/status" and Ufw don't start.

Title:
  ufw complains when ipv6 and/or ip6_tables is not available

Status in ufw package in Ubuntu:
  Fix Released
Status in ufw source package in Hardy:
  Fix Released

Bug description:
  On kernels that don't have ipv6 compiled or have it blacklisted, the
  user is presented with confusing stderr output from ip6tables, even
  though the firewall does setup IPv4 rules correctly.  Eg:

  $ sudo ufw enable
  FATAL: Module ip6_tables not found.
  ip6tables-restore v1.3.8: ip6tables-restore: unable to initialize table 'filter'

  Error occurred at line: 1
  Try `ip6tables-restore -h' or 'ip6tables-restore --help' for more information.
  WARN: problem running ip6tables
  Firewall started and enabled on system startup
