I have Ubuntu 10.10 AMD64 installed.
When I try to start the Synaptic Package Manager it attempts to start and then quits.
I have tried running it through terminal and get the following output.
roy@Bastard:~$ sudo synaptic
sudo: /etc/sudoers is mode 0640, should be 0440
sudo: no valid sudoers sources found, quitting
I get the same output for sudo apt-get update & sudo apt-get upgrade
I have looked at some of the threads on this problem but none seem to provide a solution.
Thanks in advance
