Package: ifupdown Version: 0.8.19 Severity: normal Dear Maintainer,
this bug was already reported on Ubuntu but I would like to mention I found it on Debian as well. (See https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1584682 ) Specifically, it appeared on virtual servers, which use ifupdown to change ip address when generating new server from saved image. Instead of new address replacing the other, it was added and the old address remained on the interface. The /etc/network/interfaces was changed correctly, however see ip addr list output: 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether bc:76:4e:10:38:f5 brd ff:ff:ff:ff:ff:ff inet 198.61.174.85/24 brd 198.61.174.255 scope global eth0 valid_lft forever preferred_lft forever inet 104.130.217.167/24 brd 104.130.217.255 scope global eth0 valid_lft forever preferred_lft forever inet6 2001:4801:7828:101:be76:4eff:fe10:38f5/64 scope global valid_lft forever preferred_lft forever inet6 fe80::be76:4eff:fe10:38f5/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether bc:76:4e:10:3a:55 brd ff:ff:ff:ff:ff:ff inet 10.209.101.65/19 brd 10.209.127.255 scope global eth1 valid_lft forever preferred_lft forever inet 10.210.195.129/19 brd 10.210.223.255 scope global eth1 valid_lft forever preferred_lft forever inet6 fe80::be76:4eff:fe10:3a55/64 scope link valid_lft forever preferred_lft forever The addresses 198.61.174.85/24 and 10.209.101.65/19 are old ones which should've been replaced.
