[SOLVED] Segmentation faulty tree... 50%

[master5o1]

I get this 'Segmentation faulty tree... 50%' error when I try to upgrade/safe-upgrade in apt-get/aptitude, or when I try to open Synaptic or update-manager.

Can you post your /etc/apt/sources.list?


cat /etc/apt/sources.list

[master5o1]

It appears to be fixed...after a restart AND after a suspend/resume :S

I have this error now too, would be nice to know what is causing it.

This is the second time this is happening.

I'm sorry, should have searched a bit better.
The solution seems to be

sudo rm /var/cache/apt/*.bin

as they figured out here:
