Not needed, there's a new ifblacklist_migrate.sh available in the
quantal package already; I'll just need to fix it up for a Precise SRU.

Title:
IPv4 connectivity broken after installing from ubuntu-12.04-alternate-
amd64.iso
Status in “network-manager” package in Ubuntu:
Fix Released
Status in “network-manager” source package in Precise:
Confirmed
Bug description:
To reproduce:
- Download ubuntu-12.04-alternate-amd64.iso, sha256sum:
f8d54df0afbab6a6248f6e2bcab3e68f01c04d52b0bb1f889d880ad3bc881ccb
- Burn it to a USB flash drive from a completely up-to-date Ubuntu 10.04 LTS
with UNetbootin
- Install on a machine with both IPv4 and IPv6 connectivity
- Log in to the newly installed system
Current behaviour:
- There is no IPv4 connectivity
- NetworkManager doesn't show the wired interface in its dropdown
Expected behaviour:
- There is IPv4 connectivity
- NetworkManager does show the wired interface in its dropdown
Thoughts:
I suspect this is because during the install my /etc/network/interfaces was
created like so:
---BEGINS---
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto
---ENDS---
Then network-manager-0.9.4.0/debian/ifblacklist_migrate.sh mutates the file
to comment out a single line like so:
#NetworkManager#iface eth0 inet dhcp
i.e. the line
iface eth0 inet6 auto
remains intact
This means that the /etc/network/interfaces file gives me IPv6
connectivity but not IPv4 connectivity. Furthermore, because there is
an uncommented iface eth0 inet6 line, NetworkManager doesn't show me
the interface in its dropdown.
To fix:
- The regular expression needs to be changed so that the iface eth0 inet6
auto line is also commented out
