Public bug reported:
Binary package hint: postfix
newaliases fails on a system with no IPv4 address configured, even when
it has full connectivity on IPv6.
as can be seen, this box has NO IPv4 address, but both loopback and eth0
have an IPv6 address configured:
[22:10|r...@ipv6 ~]
# ip addr ls
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state
UNKNOWN qlen 1000
link/ether 54:52:00:4c:e9:e7 brd ff:ff:ff:ff:ff:ff
inet6 2001:7b8:3:47:5652:ff:fe4c:e9e7/64 scope global dynamic
valid_lft 2591969sec preferred_lft 604769sec
inet6 fe80::5652:ff:fe4c:e9e7/64 scope link
valid_lft forever preferred_lft forever
Running newaliases fails:
[22:10|r...@ipv6 ~]
# newaliases
newaliases: fatal: could not find any active network interfaces
Adding 127.0.0.1 to the loopback interface fixes it:
# ip addr add 127.0.0.1/8 dev lo
[22:13|r...@ipv6 ~]
# newaliases
[22:14|r...@ipv6 ~]
#
(tadaa.wav, no error)
This was tested on Ubuntu 9.04, haven't checked a 9.10 install yet.
# lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04
PS: I totally understand that IPv6 only systems are still very uncommon and
thus this bug will get a very low priority, but they won't be in a few years. I
found this bug when testing systems with IPv6 only configured.
