I am getting this error message when I try to do software update. Also there is an [X] icon on the gnome bar at top. I have attached the error message in the thread.
Please help me in resolving this issue.
I have checked the path which shows in the error /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_quantal-security_universe_i18n_Translation-en this file exists and I am not sure why I am getting this error message.
