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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1044361 Title: ufw crashed with Perhaps iptables or your kernel needs to be upgraded. in get_netfilter_capabilities() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ufw/+bug/1044361/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
