Whenever I try to install or remove something using terminal it gives the following error message:
bluebird@bluebird:~$ sudo apt-get update
sudo: /usr/lib/sudo/sudoers.so must be only be writable by owner
sudo: fatal error, unable to load plugins
bluebird@bluebird:~$ sudo apt-get remove vlc
sudo: /usr/lib/sudo/sudoers.so must be only be writable by owner
sudo: fatal error, unable to load plugins
Recently I had to change the folder permissions of /usr folder. Now the whole sudo is not working.
Whenever I try to do anything at all that requires my password it returns this:
u7ur7l3@ubuntu:~$ sudo
sudo: /usr/lib/sudo/sudoers.so must be owned by uid 0
sudo: fatal error, unable to load plugins
u7ur7l3@ubuntu:~$
So I can't install anything from the Software Center / package manager or run any commands in terminal that require my password.
sudo does not work.
I have installed Arch onto a USB key, using BTRFS.
The output of "sudo" is:
$ sudo
sudo: unable to stat /etc/sudoers: Permission denied
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
$ ls -l /etc/sudoers
-r--r----- 1 root root 2849 May 18 15:00 /etc/sudoers
$ lsattr /etc/sudoers
--------------- /etc/sudoers
$ strace -u ross sudo true
I have changed the permissions of some system folders and now when i want to install a program it shows this error:
sudo: /etc/sudoers is world writable
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
Any help?
Following the wiki's advice, I installed ubuntu-zfs.
I'm configuring sudo module in puppet according to this code
class sudo {
package { sudo:
ensure => present,
}
if $operatingsystem == "Ubuntu" {
package { "sudo-ldap":
ensure => present,
require => Package["sudo"],
}
}
file { "/etc/sudoers":
owner => "root",
group => "root",
mode => 0440,
source => "puppet://$puppetserver/modules/sudo/
I'm using a git post-update hook to run a command via sudo, and I get the error: sudo: sorry, you must have a tty to run sudo. I believe I need to modify /etc/sudoers but I don't know how to do this. Any help would be appreciated!
I've set up sudo not to prompt for password by editing the sudoers file:
myuser ALL=(ALL:ALL) NOPASSWD: ALL
And it works fine, running sudo with no password prompting. But when entering sudo -v I noticed that it prompted for password, only once.
