The problem: Each time I try to execute the sudo command, and type the correct password, it rejects the password.

I am at the end of my rope with internet searches, I’m close to just wiping and trying an operating system reinstall.

I am new to linux and I recently installed ubuntu 22.04.3. I haven’t been able to access the sudo command since the install. I’m currently attempting to install firewalld, but I’m going to need this command for other things as well and I’m starting to wonder if there is something wrong with my install or worse.

Many of the troubleshooting techniques I’ve come across contain a catch 22 in that they require the sudo command to solve this, which I am unable to execute.
