I ran something like:

sudo chmod -R 777 /.

In my Ubuntu 16.04 LTS it shows many errors on display, but anyway, the damage was done. Now I can't use sudo

sudo: error en /etc/sudo.conf, línea 0 mientras carga plugin 'sudoers_policy'
sudo: /usr/lib/sudo/sudoers.so sólo tener permisos de escritura por el propietario
sudo: error fatal, no se puede cargar los plugins

And besides of that I'm nervous about what else I have broken.

Is there a way to reestablish the right permissions of the system files?

I apologise for the English, that is not my native language.

  • yep, it is the same, is there a way to merge both in one, or it's better to left both?

The only way to undo that would be a tedious by hand process for which you would need to know all the files original permissions. Save yourself the headache, Use a live USB/CD in conjunction with an external drive to backup your /home folder and do a clean fresh install.

  • Yes your system did not break from that, but the Operating System is in the fritz in its current state. You might click the check-mark beside my answer to mark it as accepted if it was helpful for you.

  • One more comment, I try the reinstall, and works whitout sweeping my home directory... The catch is the software center doesn't work at all, after a quick search here I reinstall the software center but it marks not a few errors, so i'm going to reinstall from zero
