Comment 5 for bug 516417

I've had a problem with a broken ecryptfs-utils that I tried to remove. The normal sudo apt-get remove ecryptfs-utils fails as does sudo apt-get -f install.

Instead I used the following sequence which seemed to have removed the necessary parts and put the update manager back to normal:

Command Sequence: (VERY CAREFUL TYPING PLEASE)

cd /var/lib/dpkg/info
sudo rm ecryptfs-utils.*
sudo dpkg --remove ecryptfs-utils

To make sure that the package manager is working okay, start it with:
sudo upate-manager -d
and make it check for updates.

This worked for me.

I suspect that ecryptfs-utils is broken for Lucid for now. Some bug fixes are apparently in the works.
