I somehow broke sudo on one of my systems and dont know how to fix it.
I looked with the visudo editor and did not find any change.
I tried fixing it by adding an admin group and adding a user to that group. Didnt resolve the problem either.
Anyone has an idea how to fix it?
All I get now is:
su: Authentication failure
Here is the visudo setup.
> # This file MUST be edited with the ‘visudo’ command as root.
> # Please consider adding local content in /etc/sudoers.d/ instead of
> # directly modifying this file.
> # See the man page for details on how to write a sudoers file.
> Defaults env_reset
> Defaults mail_badpass
> Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
> # Host alias specification
> # User alias specification
> # Cmnd alias specification

> # Members of the admin group may gain root privileges
> %admin ALL=(ALL) ALL
> # Allow members of group sudo to execute any command
> %sudo ALL=(ALL:ALL) ALL
> # See sudoers(5) for more information on “#include” directives:

I am not a fan of sudo at all and think the linux community was duped into believing it is safer for sysadmins. I disagree., but too many things now depend on it so I have to live with it.
