If apt-get crash

[Sturla Holm Hansen]

Hi, just had a wonderful experience with apt-get while running a
dist-upgrade....
It crashed after installing a couple of hundred packages, leaving my
system with dual installs of those packages.
What I had to do was manually remove all the packages not needed, or at
least that was what i ended up doing.
Just wondered if anyone has a better solution for this, is there a tool
for checking for dual installs and removing the lowest version?
