[SOLVED] Bad update

[driven1]

I was installing the latest updates when the update manager suddenly quit. Now, I can't get it to run at all. I tried to run

sudo apt-get install -f
but after reading the package lists it comes back with

segmentation tree faulty...50%

Anyone what I should do to fix this?

Try removing or moving out of the way the /var/cache/apt/*.bin files then run
sudo apt-get update afterwards, this should regenerate the files.

worked like a charm. Any effects from removing those files permanently?

I don't think there will be any problems removing them. I haven't encountered any. You can always keep them for awhile and delete them at a later date.
