sudo: /etc/sudo.conf is group writable
I’ve made a mistake. List of commands that I typed:
sudo usermod -a -G root erp
sudo chmod g+w /etc
setfacl -R -m u:erp:rwx /etc
ssh.service of the virtual machine stopped working and when I type commands with sudo in terminal, it says sudo: /etc/sudo.conf is group writable.
And after googling for some time, it seems what I have done is similar to
chmod -R 777 /. I’m hoping that I don’t need to reinstall the Ubuntu OS on this machine. Is what I have done actually revertible?
You have enabled a recursive ACL on the entire
/etc directory. Run this to remove all ACLs recursively:
setfacl -b -R /etc
If you are still getting the error, post the output of
ls -alh /etc/sudo.conf, if it has group write you can probably remove it with
In the future, do not run commands that you don’t understand. Use something like https://explainshell.com/ or read man pages.
