After upgrading to ubuntu 16.04, whenever I run sudo apt update, I receive Reading Package List Error and for most of the archives, Failed to fetch http://. . . Empty files can't be valid archives.
Following the suggestion on Ubuntu forum when I issue the following:
sudo rm /var/lib/apt/lists/* -vf
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
things get back on track.
However after a few days I encounter the same problem again. How can I resolve this issue?
