ERROR: Problem running ip6tables

[Leon]

Error shows when I type in the following command:

sudo ufw status

My OS: Debian/Linux

[Jamie Strandboge (jdstrand)]

What is the output of the following command:

$ sudo /usr/share/ufw/check-requirements

I suspect you have disabled ipv6 in some manner. You might be able to simply use IPV6=no in /etc/default/ufw.

Hello,

Im sorry to say that I have completely wiped my Linux machine and reinstalled Raspbian and everything works fine now. I did not touch anything to do with the ip6tables beforehand. Possibly got corrupted somehow.

Thanks

Thanks for getting back to me. Glad it is working now. Since there is a lack of information, I'm going to close this bug. Please feel free to report other issues you may find.

I am getting the same error:

# ufw status
ERROR: problem running ip6tables

But the requirements check passed:

# /usr/share/ufw/check-requirements
Has python: pass (binary: python3, version: 3.8.5, py3)
Has iptables: pass
Has ip6tables: pass

Has /proc/net/dev: pass
Has /proc/net/if_inet6: pass

This script will now attempt to create various rules using the iptables
and ip6tables commands. This may result in module autoloading (eg, for
IPv6).
Proceed with checks (Y/n)?

Andreas, can you provide more details? What distribution are you using? What is the output of `lsmod`? What are the contents of /etc/ufw/*6.rules?
