I installed Debian a day ago and I'm very new to Linux please forgive me if I miss something obvious but: whenever I use sudo command it asks me for the current user password but the current user doesn't have permission to use sudo so I have to use su and run my command there but the command I installed there only works there not in my user I used popos before and I think I was the root user there because sudo worked fine how do I login as root? In my login page (sddm) there is only 1 user.
EDIT: Can I somehow don't make a normal user in the installation? what if I leave the normal user password and username empty? will there only be root user that I can login with?
