After reading the following two posts:
Trying to install an openVPN GUI messed up sudoers
Standards accounts are able to get root access using sudo without password request
I would like to learn how to perform a backup of /etc/sudoers file so that I can restore it in the event of a mess-up after installing a non-Ubuntu-package-ready software.
Any help would be much appreciated.
/etc/sudoers.d
to backup. – WinEunuuchs2Unix Aug 04 '19 at 21:14
