Ubuntu – Sudo doesn’t ask for password anymore

passwordsudo

I did not notice it but it has been quite a while since I entered the password for using sudo priviledges.

Here is my /etc/sudoers file:

#
# 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

# User privilege specification
root    ALL=(ALL:ALL) ALL

# 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:

#includedir /etc/sudoers.d
%jupiter ALL=NOPASSWD: /usr/lib/jupiter/scripts/bluetooth, /usr/lib/jupiter/scripts/camera, /usr/lib/jupiter/scripts/cpu-control, /usr/lib/jupiter/scripts/resolutions, /usr/lib/jupiter/scripts/rotate, /usr/lib/jupiter/scripts/touchpad, /usr/lib/jupiter/scripts/vga-out, /usr/lib/jupiter/scripts/wifi

This worries me because any script can now run without me having to enter the password.

I have seen the following questions, but they seem unrelated to this post:

How do I make sudo always prompt me for a password(expept for the timeout duration given in /etc/sudoers file?

P.S.: I have some aliases set in my .bash_aliases that have commands using sudo, but I hope that is unrelated to the password prompt, or is it?

Your last line is the culprit. I do not know why, maybe it's a bug or I do not know all Linux rules.

You should consider these lines:

# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.

So remove the last line and put it in /etc/sudoers.d/sudo-jupiter. Now revert back permissions on /etc/sudoers to u-x and restart the system.
