Comment 8 for bug 1467830

I tested this again today on the following:

phablet@ubuntu-phablet:~$ cat /etc/system-image/channel.ini
[service]
base: system-image.ubuntu.com
http_port: 80
https_port: 443
channel: ubuntu-touch/rc-proposed/ubuntu
device: mako
build_number: 268
version_detail: ubuntu=20151020,device=20150911,custom=20151020,version=268

It seems that the fix for LP: #1489410 makes whitelisting the PPA as I suggested in comment #2 unnecessary.
