Hello
You do as in the post #8 then you do :
adduser helena sudo
adduser helena adm
adduser helena lpadmin
adduser helena sambashare
Then you reboot

[danny7]

adduser: /usrbin/gpasswd -a helena sudo' returned error code 1. Exixting.

The group 'adm' already exists

'helena' is already a member of 'lpadmin'

'helena' is already a member of 'sambashare'

Thank you stelldriver

I entered

adduser helena admin

rebooted and voila, installing packages as we speak

And thank you everyone who posted.
