Problems with "sudo" command in Debian version 9.5 Linux.

Attention: windowsForum members:
I am having trouble with the "sudo" command. When prompted for a [sudo] password, I have tried both the Linux root password and the regular Linux password, but have no success. Also, when attempting to use the "ssh" command to log in as root, I use the same two above-referenced passwords, but receive the "Permission denied" error messages ( see the screen capture file, below, regarding the highlighted commands and error messages ):

Thank you ( see Colossians 3:15, for example ) for your help. Keep in touch.

Sincerely in Christ,

sudo allows your existing user to have root level access temporarily. With sudo you would use the password for the account you are currently logged in as. Also as indicated in the screenshot your user is not in the sudoers file you will need to add your account and logout or reboot. For ssh you would need to configure the ssh daemon to allow root login typically that is disabled.

Sudo is disabled by default in Debian due to security reasons.
Attention: livix07:
Earlier today, I used the command "adduser <username>" to add a new user, as described in the following link:
How To Create a Sudo User on Ubuntu [Quickstart] | DigitalOcean. ( Without the period at the end. ) Then I used the command "adduser <username> sudo" to add the new account to the "sudo" group, as described in the following link:
How to Fix "Username is not in the sudoers file. This incident will be reported" in Ubuntu. ( Again, without the period at the end. )
Before that, I used the command "usermod -aG sudo <username>" to add my original Linux user account to the "sudo" group ( as described in the first link, above ). Thank you ( see Colossians 3:15, for example ) for your help. Keep in touch.:)
