Can not update, sudoer issue

[hal_sk]

Hello,
I have freshly installed Debian 11.x
When I open the terminal and execute:

sudo apt update

I get "<user> is not in sudoers file".
It works in Linux Mint which I use normally.
What is happening? How do I update and upgrade Debian?

In Debian you have to add yourself to the sudoers list from the terminal run

su root

press enter then

sudo usermod -aG sudo username

where username is your user name press enter

reboot

I just solved it by reinstalling Debain. The problem was, that during my first installation process, I have set passwords for both root and user. Now I have only set password for user. Still not sure what is the point of it, but at least it works as I am used to from Mint.

The point is that not having root acount active is better for security, everyone knows root account is called root, but if you set some other username then it can't be guessed so easily.

For a long time, root was the default user on Linux, but it’s now disabled on most distributions. On Debian, using “sudo” is the recommended method to get administrator privileges with the main user, instead of using “root”. If needed, the “root” user can still be enabled by setting up their password. The “root” still exists on Debian and most Linux distributions, but can’t be used by default. The account is disabled for security reasons.
If you have access to a user account with the sudo permission, you can easily switch from the user to the root account with:

sudo su

Me I like to use root access so I have mine enabled
