sudo su: results -effective uid is not 0 is sudo installed setuid root

This another common problem for the new users for Linux. Anonymous change of permission of root or while experimenting we do run commands which results into some unexpected results.

we can observe this output while doing sudo su in linux mainly in ubuntu.

The solution lies in changing the permisions

Method 1: While booting hold on shift and from the recovery menu drop to the root shell and run the following commands

chown -R root:root /usr/bin/sudo

mount -ro remount,rw /

mount -ro remount,ro /

basically we are changing the owner and remounting to fix this error.

If this doesn,t work do opt the next method

Method 2 :pkexec chown root:root /usr/bin/sudo

pkexec chmod 4755 /usr/bin/sudo

and boot normally.

This will get you out of the effective uid error.
