What happened to my hostname?

In the past the hostname of my Aurora based laptop has been “aurora”. Recently, and I’m not sure when exactly, the hostname has become a single letter “b”. Using the hostname cli command I can set the hostname but it doesn’t stick between reboots, returning to the enigmatic “b”. What gives?

what command are you using

sudo hostname aurora

use hostnamectl set-hostname yourhostname

Yup, you beat me to it!

That did it thanks to both of you.
