Como substituir o / etc / sudoers personalizado quando não o fiz no 'apt-get upgrade'?

Question

Eu fiz sudo apt-get update && sudo apt-get upgrade . Ele passou, até que atingiu o pacote sudo, cujo arquivo sudoers é alterado. Eu chamei o diff no VIM e saí com :q . Em vez de me avisar novamente, ela tomou a ação padrão e manteve minha versão alterada.

Eu pretendia instalar a versão distribuída do pacote / etc / sudoers, como posso fazer isso em retrospecto? Eu tentei apt-get install --reinstall sudo , sem alteração.

Saída de apt-get upgrade :

   What would you like to do about it ?  Your options are:
    Y or I  : install the package maintainer's version
    N or O  : keep your currently-installed version
      D     : show the differences between the versions
      Z     : start a shell to examine the situation
 The default action is to keep your current version.
