cara mengganti update repo manual Linux

buka di terminal
sudo nano /etc/apt/source.list.d/official-package-repositories.list                       
Isinya ganti yg http:/dengan ip yg diinginkan
contoh punya saya :

deb http://192.168.1.8/linuxmint serena main upstream import backport

deb http://192.168.1.8/ubuntu xenial main restricted universe multiverse
deb http://192.168.1.8/ubuntu xenial-updates main restricted universe multiverse
deb http://192.168.1.8/ubuntu xenial-backports main restricted universe multiverse

deb http://192.168.1.8/ubuntu/ xenial-security main restricted universe multiverse
deb http://192.168.1.8/ubuntu/ xenial partners

save    = ctrl + o
              enter
keluar = ctrl + x
