[Pkg-netfilter-devel] Bug#829269: ufw: fails with ERROR: initcaps, dmesg: ip6_tables: disagrees about version of symbol xt_compat_match_from_user in a fresh install

[Brian Walsh]

I was seeing this same error message. Running modprobe ip6_tables would
generate the message.

ip6_tables: disagrees about version of symbol xt_compat_match_from_user

I had done an apt-get upgrade a while back and it looks like I had not
rebooted since that upgrade. I verified this by comparing the uptime to
the apt history of when linux-image was last installed. So I was running
a different kernel that did not match the modules on the filesystem.

I rebooted and everything was fine.

I would say this is not a bug.
