sudo - sudo: parse error in /etc/sudoers near line 23? up vote 18 down vote favorite 4 I am getting this error: sudo: parse error in /etc/sudoers near line 23 sudo: no valid sudoers sources found, quitting sudo: unable to initialize policy plugin I was trying to disable password authentication so I don't have to type password every time I want to install something, but I probably changed it in a not very good /etc/sudoers is world writable way. I am a newbie to Ubuntu, I got sick of Windows :) So far I've found some people suggesting booting in single user mode, but I'm afraid of messing things up more.

And, how exactly do I boot in single user mode? –Robert Fáber Oct 30 '12 at 11:19 2 @ObsessiveSSOℲ it would be nice to convert the comment to answer and let the questioner to mark it as the best answer.

Asked by Ceaser Webb on 2010-09-16 Tried to download virtual box and received error msg: Previous installation hasn't been completed. The installation could have failed because of an error in the corresponding https://answers.launchpad.net/ubuntu/+source/sudo/+question/125653 software package or it was cancelled in an unfriendly way. You have to repair http://serverfault.com/questions/251213/repair-a-broken-sudoers-file this before you can install or remove any further software.

Problem description: I have broken my /etc/sudoers file by making a typo in it. Now I can no longer use any sudo commands as the below error is thrown. Therefore I can't fix my sudoers file and am effectively stuck. $ sudo nano /etc/sudoers >>> /etc/sudoers: syntax error near line 39 <<< sudo: parse error in /etc/sudoers near line 39 sudo: no valid sudoers sources found, quitting I found few solutions saying I should boot into recovery mode (like the one below) which I would obviously like to avoid. Ubuntu : borked my sudoers file, how can I fix it? Questions: -Are there any other ways to fix it without restarting ubuntu? -If it is so easy to lock yourself out of sudo when modifying the sudoers file (everybody can do a typo), why isn't the sudoers config read from memory instead of the file directly? There would be a command (e.g. sudo-load) that would make sure the syntax is OK before loading the config into memory thus avoid this sort of problems. Solutions: There seems to be 2 ways of recovering it: -if you have the root password you can simply issue a 'su' and then edit the file -if you don't have the root password you need to restart into single user mode ubuntu sudo share|improve this question edited Mar 24 '11 at 9:06 asked M
