After I installed Ubuntu , I cannot update any software with the error message "failed to download package files". After having googled, I have tried:
sudo apt-get update
sudo apt-get upgrade
- changed to another sources
But I still got the same error message. And there is no problem with internet connection as i can connect to internet using Firefox in Ubuntu.
Any ideas?

Press Alt+F2 and type
software-properties-gtk
.Change the download location to Main Server or another server close to the country you live in and try to
sudo apt-get update
again.
