Answer 1

This applies to those environments where they have a docker/Kubernetes environment running and have a host root file system mounted into the container or pod.

In this case, the host's root / is mounted as /host inside the pod.

kubectl exec -it mypod -- chown root:root /host/usr/bin/sudo && chmod 4755 /host/usr/bin/sudo

I have not tried creating a fresh Kubernetes pod but I guess, that should work too.

Answer 2

This is my first time as Ken-Andre to write on this channel, because all answer gave here semms so difficult, where for my case i found on other channel, more easier:

1. systemd-run --shell
2. chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo

Hope, that it will work for you too.

This worked for me to hanldle this issue I used this command to become a root user:

systemd-run --shell

after that: chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo

If you have root user password then:

2.open terminal

3.Enter following cmd's:-

mount -o remount /
chown root:root /usr/bin/sudo && chmod 4755 /usr/bin/sudo
chown root:root /usr/lib/sudo/sudoers.so && chmod 4755/usr/lib/sudo/sudoers.so
chown root:root /var/* && chmod 4755 /var/*

If you do not have root user password then:

1.Reboot your system in recovery mode(boot and press and hold esc button to enter in recovery mode)

here it looks like

2.Nevigate to (advance option for linux) by using down arrow button and press two times Enter

here it looks like

3.Nevigate to root by using down arrow button and press Enter

here it looks like

4.Now enter following cmd's:-

Answer 8

This worked for me

“sudo: /usr/bin/sudo must be owned by uid” Or sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set. Reason :This error occurs when incorrect permission or ownership is set on /usr/bin/sudo file.

Solution

Step 1 : Start the server in Single user mode using command at start.

1. init 1

Step 2 : Once single user mode starts use below commands

1. mount -o remount,rw /
2. - chown root:root /usr/bin/sudo
3. - chmod 4755 /usr/bin/sudo

Step 3: Now Reboot the Server and check.

1. reboot //(linux command line)

Answer 10

To solve this issue, you need to boot into recovery mode which provides a scroll-down menu with an option to drop down to a root shell.

And type these commands one after another:

# remount disks in read-write mode
mount -o remount,rw /
mount --all

# return ownership
chown root:root /usr/bin/sudo

# fix permissions
chmod 4755 /usr/bin/sudo

After that, you can reboot and log in again.

You may try this, to know if It worked:

sudo -l

Answer 11

Simple fix

1-

2-select recovery

3-select root

4-mount -o remount,rw /

5-chmod u=rwxs,g=rx,o=rx /usr/bin/sudo /usr/bin/pkexec

6-reboot or exit

First restart your pc, and press the ESC key while Ubuntu is booting.

This will bring you up the boot menu.

Select Advanced Options.

Select your OS version in (recovery mode), and press Enter Key.

It will bring you up another screen. Now select “Drop to root shell prompt” and press Enter.

It will load a command line at the bottom of the screen.

Now run each of the following commands.

mount -o remount,rw /
mount --all
chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
shutdown -r now
