aptitude does not let you install local debs and dkpg doesnt fix dependencies so either

aptitude install libqtcore4 libqtgui4 libqt4-network

before you run dkpg or

aptitude install gdebi

and use gdebi or gdebi-gtk to install synergy-1.4.18-r2250-Linux-x86_64.deb

ubuntu alternatives

as well as the select-editor command ubuntu update-alternatives lets you make your favorite browser, texteditor etc your default

find out what your default apps are currently with

$ su -
# update-alternatives --get-selections

use update-alternatives –config to interactively change a single alt

$ su -
# update-alternatives --config x-terminal-emulator

or if you have a lot of spare time you can set ALL your favorite default apps

$ su -
# update-alternatives -all

if you are running @virtualbox 4.2.12 and have an ed/k/x/ubuntu 12.04.02 LTS guest with virtualbox guest additions installed do not allow the the kernel to be updated to 3.2.0-43

other possible workarounds

  • downgrade virtual box to 4.2.10
  • do not install virtual box guest additions
  • use guest additions from ubuntu repo instead of virtual box iso
