16.04.1 Ошибка LTS при обновлении apt-get

Я получаю ошибку при обновлении:

al@alpc:~/android$ sudo apt-get update
...
Err:15 http://archive.ubuntu.com/ubuntu saucy/universe amd64 Packages
  404  Not Found [IP: 91.189.88.149 80]
...
E: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/saucy/universe/binary-amd64/Packages  404  Not Found [IP: 91.189.88.149 80]

Googling дает мне, что эта ошибка происходит при использовании старых выпусков Ubuntu, но я использую недавно загруженные 16.04.1:

al@alpc:~/android$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:    16.04
Codename:   xenial

[d2 ] Я пытаюсь это сделать, потому что я не могу установить mingw32:

al@alpc:~/android$ sudo apt-get install mingw32
Reading package lists... Done

E: Unable to locate package mingw32

Вот мой /etc/apt/sources.list:
