On a MEPIS 8.5 amd64 system, I followed the lenny instructions at http://www.trinitydesktop.org/installation.php#debian and all worked except sudo apt-get install desktop-base-trinity kde-trinity Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: kde-trinity: Depends: kde-core-trinity (>= 5:47) but it is not going to be installed Depends: kdeedu-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdegames-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdetoys-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdeaccessibility-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdeaddons-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdeadmin-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdeartwork-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdegraphics-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdemultimedia-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdenetwork-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdepim-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdeutils-trinity (>= 4:3.5.5) but it is not going to be installed Depends: kdewebdev-trinity (>= 4:3.5.5) but it is not going to be installed E: Broken packages Some help would be appreciated.
