Ubuntu has so many mirror repository we can choose. Sometimes the mirror exists in our country that near with our internet provider.

Update

Thank to this answer on askubuntu.com we can automatically select fastest (maybe) mirror based on our geographic location.

This configuration will automatically select best mirror based on our geographic location. However, this doesn’t necessary mean the fastest server. Add following entry at the top of /etc/apt/source.list file. You may delete other entry if you wish.

deb mirror://mirrors.ubuntu.com/mirrors.txt xenial main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-updates main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-backports main restricted universe multiverse
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial-security main restricted universe multiverse

Change xenial part with your ubuntu version such as trusty, artful, bionic.
