I just start using rpi and quite a newbie
i run
sudo apt-get update
sudo apt-get upgrade
The update thing is successful, however , i cannot do the upgrade part,
there are some package they fail to fetch
It's said Failed to fetch http://mirror.nus.edu.sg with hash sum mismatch
I did some searching and found out that this mirror only limited in NUS campus. But how to change to other mirror, as i go to /etc/apt/sources.list. The url there is archive.raspbian.org which is nothing related to the NUS thing but my pi keep fetching from NUS mirror.
Please help
