DO NOT USE apt-get update and apt-get upgrade from the command line. This has never been recommended. If you insist on using the command line, the correct procedure is apt-get update and apt-get dist-upgrade. If for any reason the system says it is not able to retrieve a package do you wish to continue always say no, report it to the forum and try to update again later.
