I had the same problem  Even after updating the password using sudo passwd it was not working  I had to give  multiple  roles for my user through IAM  amp  Admin Refer Screen Shot on IAM  amp  Admin screen of google cloud  After that i restarted the VM  Then again changed the password and then it worked   user1 sap-hanaexpress-public-1-vm   gt  sudo passwd New password   Retype new password   passwd  password updated successfully user1 sap-hanaexpress-public-1-vm   gt  su Password   sap-hanaexpress-public-1-vm  home user1   whoami root sap-hanaexpress-public-1-vm  home user1

This work at least in the Debian Jessie image hosted by Google  The way to enable to switch from you regular to the root user  AKA    super user     after authentificating with your Google Computer Engine  GCE  User in the local environment  your Linux server in GCE  is pretty straight forward  in fact it just involves just one command to enable it and another every time to use it    sudo passwd Enter the new UNIX password   lt your new root password gt  Retype the new UNIX password   lt your new root password gt  passwd  password updated successfully  After executing the previous command and once logged with your GCE User you will be able to switch to root anytime by just entering the following command    su Password   lt your newly created root password gt  root intance     As we say in economics    caveat emptor    or buyer be aware  Using the root user is far from a best practice in system   s administration  Using it can be the cause a lot of trouble  from wiping everything in your drives and boot disks without a hiccup to many other nasty stuff  that would be laborious to backtrack  troubleshoot and rebuilt  On the other hand  I have never met a SysAdmin that doesn   t think he knows better and root more than he should  REMEMBER  We humans are programmed in such a way that given enough time at one at some point or another are going to press enter without taking into account that we have escalated to root and I can assure you that it will great source of pain  regret and extra work  PLEASE USE ROOT PRIVILEGES SPARSELY AND WITH EXTREME CARE  Having said all the boring stuff  Have fun  live on the edge  life is short  you only get to live it once  the more you break the more you learn

I tried  quot ManiIOT quot  s solution and it worked surprisingly  I ve added another role  Compute Admin Role  for my google user account from IAM admin  Then stopped and restarted the VM  Afterwards  sudo passwd  let me to generate a new password for the user  So here are steps   Go to IAM  amp  Admin Select IAM Find your user name service account  basically your google account  and click Edit-member Add another role -- gt  select  Compute Engine  -  Compute Admin  Restart your Compute VM open SSH shell and run the command  sudo passwd  enter a brand new password  Voil

Figured it out  The VM s in cloud engine don t come with a root password setup by default so you ll first need to change the password using     sudo passwd   If you do everything correctly  it should do something like this   user server     sudo passwd Changing password for user root  New password   Retype new password   passwd  all authentication tokens updated successfully
