a real upgrade mess

upgrade on my notebook machine went relatively uneventfully, so i thought it safe to upgrade desktop machine. and boke everything to the extent that i do not have x on the desktop machine at all. am running ubuntu-12.04LTS from a terminal, having added the specified lines to my sources.list and commented out the old tde lines, i did: sudo apt-get update sudo aptutide upgrade due to server congestion i had to run the latter several times. it then specified a problem, to be solved by removal of libcal2b-trinity and libqt-perl. the installation blows up in a fashion too long to list here -- i'd have to type it in character by characer, and it includes "25 not fully installed or removed" when i went back at it with sudo apt-get dist-upgrade. that command blows up with: dpkg: error processing /var/cache/apt/archives/tdelibs-data-trinity_4%3a14.0.0-r1231-0ubuntu12.04.0+pr138_all.deb (--unpack): trying to overwrite '/opt/trinity/share/icons/crystalsvg/16x16/devices/cdrom_unmount_encrypt.png', which is also in package kdebase-kio-plugins-trinity 4:3.5.13.2-0ubuntu12.04.0+0 dpkg-deb (subprocess): data was killed by signal (Broken pipe) dpkg-deb (subprocess): error: subprocess <decompress> returned error exit status 2 Errors were encountered while processing: /var/cache/apt/archives/tdelibs-data-trinity_4%3a14.0.0-r1231-0ubuntu12.04.0+pr138_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1) not real sure how to proceed. ideas? thanks. -- dep The shortest distance between you and great fingerstyle guitar playing?
