It seems my droplet has this error

“sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set”

And can’t access it via Putty also. I think my permissions rights is corrupted Is there a way I can fix this? Thanks

I sudo chown to give another user to access all folders in system

I too ran into the same issue…and thanks to this blog post I solved it :)

Here’s how to do it, I hope somebody will find this useful…

In ubuntu recovery mode, enter the following commands…

mount -o remount,rw /

mount --all

chown root:root /usr/bin/sudo

chmod 4755 /usr/bin/sudo

restart

That’s it…it worked for me…
