Hadn't thought of using the apt-get dist-upgrade

kde-trinity 3.5.13, although I did use it as instructed to upgrade from
Lenny to Squeeze. It is too late now to find out whether using apt-get
dist-upgrade for the first attempt to upgrade to 3.5.13 would have
avoided the problem I encountered.
Probably yes.
<man apt-get>
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 update must be performed first so that
apt-get knows that new versions of packages are available.
dist-upgrade
dist-upgrade in addition to performing the function of upgrade,
also intelligently handles changing dependencies with new
versions
of packages; apt-get has a "smart" conflict resolution
system, and
it will attempt to upgrade the most important packages at the
expense of less important ones if necessary. So, dist-upgrade
command may remove some packages. The /etc/apt/sources.list file
contains a list of locations from which to retrieve desired
package
files. See also apt_preferences(5) for a mechanism for
overriding
the general settings for individual packages.
