If I try to run it the usual way, the dialog asking me to enter my password appears but then instantly disappears, it kind of flickers... Guess it will have to do.

Did you try using gksudo? Sadly I am unable to reproduce your problem. Everything works fine for me. Technically the sudo command shouldn’t be used for GUI apps. Did you try using gksudo?

Then, I changed the permission of sudo and sudoers. I can install packages from the terminal and I can execute commands using sudo but it seems that if I try to do stuff that requires su permission OUTSIDE of the terminal, for example: installing software from ubuntu software center, I don't get a dialog box asking me to enter my password. I have no idea why... I’ve set the permission for all diskless files to 777. Then, I changed the permission of sudo and sudoers.

Given what you've discovered, are the permissions for all the diskless files set correctly on your server? If you can't install new packages, then that suggests you are not able to write to the NFS drive.

There another problem that I think is related and that is I can't install sodtware from the Ubuntu Software Center. I click INSTALL but it doesn't pop up the usual dialog asking me for my password. Any advice on that? Got it sorted by changing the premissions on server side using:
chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
