Thank you for using Ubuntu and filing a bug. Your kernel doesn't seem to have
the required iptables support:
Traceback (most recent call last):
File "/usr/sbin/ufw", line 95, in <module>
ui = ufw.frontend.UFWFrontend(pr.dryrun)
File "/usr/lib/python3/dist-packages/ufw/frontend.py", line 153, in __init__
self.backend = UFWBackendIptables(dryrun)
File "/usr/lib/python3/dist-packages/ufw/backend_iptables.py", line 45, in
__init__
ufw.backend.UFWBackend.__init__(self, "iptables", dryrun, files)
File "/usr/lib/python3/dist-packages/ufw/backend.py", line 81, in __init__
nf_caps = ufw.util.get_netfilter_capabilities(self.iptables)
File "/usr/lib/python3/dist-packages/ufw/util.py", line 734, in
get_netfilter_capabilities
raise OSError(errno.ENOENT, out)
OSError: [Errno 2] FATAL: Module ip_tables not found.
iptables v1.4.12: can't initialize iptables table `filter': Table does not
exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
I noticed that you are using a non-Ubuntu kernel '3.5.1-pfz3'. Please
recompile with the necessary kernel support. You might want to use
/usr/share/ufw/check-requirements to help identify what you need.
** Changed in: ufw (Ubuntu)
Status: New => Invalid
