[pkg-netfilter-team] Bug#916596: iptables.postinst failure on link creation

[Olivier]

Package: iptables
Version: 1.8.2-2+b1
Severity: important

Dear Maintainer,

Issue occure during iptables:i386 1.8.2-2 -> 1.8.2-2+b1 upgrade.

/var/lib/dpkg/info/iptables.postinst fail with message:

ln: failed to create symbolic link ''$'\t''      /sbin/iptables-save': No such file or directory

The root cause is here :

<script>
        LIST="/sbin/iptables
              /sbin/iptables-save
              /sbin/iptables-restore
              /sbin/ip6tables
              /sbin/ip6tables-save
              /sbin/ip6tables-restore"

	for i in $LIST ; do
</script>

There are tabs before "/sbin/", so this cause "for i in $LIST" issue (tabs are used as a file name)

Workaround: Remove tabs:

<patch>
        LIST="/sbin/iptables
/sbin/iptables-save
/sbin/iptables-restore
/sbin/ip6tables
/sbin/ip6tables-save
/sbin/ip6tables-restore"
</patch>

	Issue are similar with #914074 and #914129, but not exactly the sames.

	Thanks for your help.

	Best regards,
					Olivier
