How To Troubleshoot Sudo Parsing Error In /etc/sudoers.d Problems

 

Here are some simple ways that you can help resolve the sudo parsing error in the /etc/sudoers.d problem.

 

 

On a good, modern and reliable Ubuntu system (and many other GNU / Linux distributions), recovering a corrupted sudoers file is actually quitesimple and does not require a reboot with a CD or physical access to your own computer.

To do this, connect via SSH to the machine using a diary and run the command pkexec visudo . If the person has physical access to the device, SSH is not required; Just open a nice terminal window and run the command pkexec who.

Assuming that you (or an additional user) are allowed to run programs as long as you are root with PolicyKit, you can enter your password, and then it could be visudo , for example root and you can restore your / etc / sudoers .

If you need to edit one of the layout files / etc / sudoers in.d (which is unconventional in this situation, perhaps), but pkexec visudo -f / etc / sudoers. r / filename .

If you may have a similar situation where you need to follow some additional sysadmin instructions to solve a big problem (also unusual in these circumstances, fortunately in other cases), you might consider an interactive root shell using pkexec-bash . Typically, any non-graphical descriptor that you execute with sudo can be executed with pkexec .

(If there is more than one user account on the system that is allowed to run when programs with PolicyKit are root , each of these actions will actually ask you to choose which one your company wants to use. as you are prompted for a password.)

If that never works – for example, if there are no Internet users allowed to run programs as a base using PolicyKit – then you boot from an Ubuntu Live CD (like a CD that you probably used to install Ubuntu yourself) and also mount the filesystem for the configured system. You can do this by running sudo parted -l to display your partitions – there is probably only an ext4 partition and this is the main root filesystem. v

The body of the Ubuntu installed is assumed to be the root filesystem at / dev / sda1 . Then you can mountAdd it to sudo mount / dev / sda1 / mnt . Then manually edit the sudoers of the installed system with sudo -w nano / mnt / etc / sudoers . Or better yet, you can do it with

. edit

  sudo visudo -f / mnt / etc / sudoers  

The

(which protects you from keeping the sudoers syntax list) is incorrect.

By giving sudo permission to the exception, the user made a mistake, saved it, and closed it before I knew about it. Later, when trying to provide sudo -s , the following error slogan was encountered. I cannot open the sudoer image and edit it again to understand it.
