I have installed Debian 10 on Dell Inspiron with an AMD processor. I am using the KDE Plasma desktop. When I try



sudo dpkg  -i ./palemoon_28.6.1+repack-2_amd64.deb


I get



[sudo] password for peter: 
peter is not in the sudoers file. This incident will be reported.


I logged in as root and entered



/usr/sbin/adduser peter


This returned



adduser: The user `peter' already exists.



I then tried the following as root



chmod 0440 /etc/sudoers


When I try to sudo, in the peter account, I still get



peter is not in the sudoers file.  This incident will be reported.


I then try the following as root



sudo usermod -aG sudo,adm peter


Still get the same reslt when I try to sudo from the peter account.



Opening a new terminal, for the peter account, does not change anything.
