Hello Alex, I would guess that the reason why the permissions are incorrect is probably whatever tool added four copies of this to your sudoers:
ALL ALL=(ALL) NOPASSWD:/usr/share/dtsremoter/remoterserver ALL ALL=(ALL) NOPASSWD:/usr/share/dtsremoter/remoterdelegate Any tool that would do that is probably pretty poorly written. That's my guess where to lay blame. If you don't have any open root command shells, I suggest rebooting into a recovery mode to change the permissions on the file. If you get the same "Operação não permitida" response, try chattr -i /etc/sudoers and then try again.

I don't have any idea on how it was changed, and I tried many different ways to chmod it and I didn't get to do it, even booting from another media and trying to chmod the file didn't work. It's the main reason of the many errors that started happening when updating this machine. I can't stop this machine now, and I don't want to run the risk of trying to use the installation software to try to repair it. If you have any idea on how to chmod the file, I'll be grateful.
