[Pkg-utopia-maintainers] Bug#931722: Firewalld fails when startig and when reloading rules

[Ramón García]

Package: firewalld
Version: 0.6.3-5

When one runs firewall-cmd --reload, and when firewalld starts, the
following error appears


2019-07-09 17:02:15 ERROR: '/usr/sbin/iptables-restore -w -n' failed:
iptables-restore v1.8.2 (nf_tables):
line 4: RULE_REPLACE failed (No such file or directory): rule in chain INPUT
line 4: RULE_REPLACE failed (No such file or directory): rule in chain OUTPUT


Fix:

The cause of the bug is that iptables restore fails when both -F and
-Z are applied in the same table (see
https://bugzilla.redhat.com/show_bug.cgi?id=1664829 )

In file /usr/lib/python3/dist-packages/firewall/core/ipXtables.py
remove the flag -Z
