Invalid code name in elementary.list and patches.list

[Jung-Kyu Park]

It happens to me almost every time at fresh installation of Loki Beta with Daily
The code name in /etc/apt/sources.list.d/elementary.list and /etc/apt/sources.list.d/patches.list
It should be "xenial" instead of "loki" there.
But, almost every time, there is "loki" instead of "xenial"
It makes system unable to update or upgrade after installation.
It happened from Luna, Freya and now to Loki.

I am Multibooting with Windows 10 and Freya and Linux Mint with Loki in one SSD
EFI for Windows 10 (/dev/sda2) , Freya to MBR (/dev/sda) to manage Grub mainly, others are each partitions
like (/dev/sda7, /dev/sda8, /dev/sda9) to test Beta of their version in same condition.
Using Gparted to format and label partiton for Loki (/dev/sda9)

but it happens to not only this test machine but also macbook Pro, and other laptop with only Freya at that time.

1) before entering ubiquity I choose language Korean at right after booting up installation USB
2) Checking option for mp3 and wi-fi
3) Others - Define / to (/dev/sda9) without format - since I have already formatted using with Gparted first.
4) Boot loader to (/dev/sda9) due to manage Grub in Freya at MBR
5) Seoul
6) Name, Username, Passwd
7) First boot after clean install. I always check this first ,
The code name in /etc/apt/sources.list.d/elementary.list and /etc/apt/sources.list.d/patches.list
8) If there is "loki" instead of "xenial" , Can't update & upgrade

# add line to above comment
4.5) Keyboard Korean
6.5) Boot up to Freya to update grub to define Loki now installed, $ sudo update-grub ,reboot

I fresh-installed the stable release on 29/09/2016 but the problem existed for me too.

One Command line for workaround before first repo update
$ sudo sed -i 's/loki/xenial/g' /etc/apt/sources.list.d/elementary.list /etc/apt/sources.list.d/patches.list
$ sudo apt update
