Technically it is safe to use
apt-get -f upgrade
upgrade packages currently installed with new versions available are retrieved and upgraded; under no circumstances currently installed packages are removed, or packages not already installed retrieved and installed.
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. The dist-upgrade
command may therefore remove some packages.
so basically dist-upgrade would install or remove packages as necessary to complete the upgrade and is more likely to break stuff badly than upgrade .
So could not say but it might conflict with EE , depending upon os version you are using .
