XY: I installed bazzite and goofed up. The username is wrong and my home is /home/bazzite instead of /home/ludrol
I am trying to run usermod -l ludrol bazzite in tty3 with sudo su - but the bazzite user is logged.
Solution:
Added password to root with passwd
Logged in as root
Ran required usermod commands
Disabled root with passwd -l
Create a new user with sudo access then log in as that user and make the change. When done delete the temp user.
Thank you
