How can I restore root account that is running on EC2 Ubuntu platform?

In the /etc/passwd the root username got replaced with something like this – “text with space”
Now I cannot log in using the root password. I was able use a user account to login but this user account does not have any admin privs.

Please help.

My answer:

You enable the root account on Ubuntu by first reading the strong warnings in the documentation, and then if you still want to proceed…

sudo passwd root

If the /etc/passwd file is corrupt, you can fix it by running

sudo vipw
