Hi All
Accidentally I changed the ownership of all the directories under / to my own instead of root:root.
Now I am unable to use sudo and many bad things are happening.
Is there a way to revert the changes or change the permissions again to root:root or make sudo work ?
TIA
asd

Tsk. Boot a rescue disk, mount the appropriate partition/file system, and fix
the ownership.
You do not need sudo to become *root. *Use
su -
in a terminal (maybe best in the console itself in this case). It asks of course for the root password (you will not see any echo of this).
When it is only the directories direct under / then you can make root the owner again, but when you use the -R option and thus changed all inside, you have a big problem.
EDIT: it is not clear what you exactly changed. In the title you say /etc/sudoers, but in the text all inside /, that is also /etc, but not /etc/sudoers. ???

In lieu of a rescue disk it may be worthwhile to try the following on the
end of your Grub line while booting which should just drop you to a prompt:
init=/bin/bash
Once there, fix your sudoers file and reboot to see if it’s all better.
chown root:root /etc/sudoers
chmod 440 /etc/sudoers
Good luck.
