The packages may have been made obsolete by other packages with different names.
You may want to try and upgrade, rather than an update. From Debian.org :

update
update is used to resynchronize the package overview files from their sources. The overviews of available packages are fetched from the location(s) specified in /etc/apt/sources.list. For example, when using a Debian archive, this command retrieves and scans the Packages.gz files, so that information about new and updated packages is available. An update should always be performed before an upgrade dist-upgrade.

upgrade
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An apt-get update must be performed first so that apt-get knows that new versions of packages are available.
