I created an instance with Debian 9 and was following the instructions on Google's site [here](https://cloud.google.com/solutions/chrome-desktop-remote-on-compute-engine). I have done this before successfully. All was going fine, but now when I do this part:

```
DISPLAY= /opt/google/chrome-remote-desktop/start-host \
    --code="4/xxxxxxxxxxxxxxxxxxxxxxxx" \
    --redirect-url="https://remotedesktop.google.com/_/oauthredirect" \
    --name=

```

I get the error 

> 
> Adding user newuser\_gmail\_com to group chrome-remote-desktop
>  ERROR:Failed to access chrome-remote-desktop group. Is the user a
>  member?
> 
> 
> 

Can anyone help me out here? I notice that when I did this previously, the username create was not newuser\_gmail\_com, but rather simply newuser. Any suggestions you have would be much appreciated. Many thanks!
