Thanks to both,,, but that was not what I was looking for. What I was looking 
for was to make a *buntu work like a "normal" Debian and ask for the *root* 
password instead of the *user* password.

Funnily, I could not find an answer to this directly. I found people letting 
their user use sudo without password (!), or answers about setting the root 
password and the root account. I knew about sudo passwd root and how to be 
able to log as root (which I very seldom use).

After much reading and using this Deepin install to test and try, I think I've 
found:

- create the root password as Chris wrote
- Follow Dan's suggestion if you want
- add this to sudoers:
"Defaults rootpw"

Funny enough, once you've found that and search for "Default rootpw" you find 
a lot of interresting stuff, includind requiring the user to use his wn 
password for specific commands...

So it was probably me not searching the right way :)
Linux is real fun (and TDE rules)  :))

Have a great day!
