I just considered upgrading a slink server here to potato. I apt-get updated and then ran apt-get dist-upgrade.
exim is held back, because libopenldap1 is uninstallable, because libopenldap-runtime is uninstallable, because debconf is uninstallable, because perl-5.004* is to be installed rather than perl-5.005. That's pretty ugly... ! A simple 'apt-get upgrade' lists over a pageful of packages which are to be held back. Trouble ahead? Hamish -- Hamish Moffatt VK3SB.
