I hardly believe an update will change the right to /etc.

Did you use chmod?

Check with
ls -l /
what the rights are for these directories en change them from rwxrwxrwx to rwxr-xr-x

ok i changed it but i cant use sudo anymore now?

Code:

sudo: /etc/sudoers is mode 0755, should be 0440
sudo: no valid sudoers sources found, quitting

Reboot from a LiveCD, and mount the partition in question.

Code:

sudo mkdir /mnt/drive
sudo mount -t ext4 /dev/sda1 /mnt/drive

Replace /dev/sda1 and ext4 with the appropriate partition and filesystem type (you can find these out by opening the Partition Editor). Then chmod the etc/sudoers inside the mount point.

Code:

sudo chmod 440 /mnt/drive/etc/sudoers

Reboot and it should work.

If you didn't make the change in permissions on all those directories in the first place, then it would be a good idea to reinstall the OS completely and restore from backups. This would not have been caused by any updates from the repositories.

Even if you did make the initial changes it might be faster to reinstall than to go back through and identify everything that has been messed up and correct it.
