[clug] hostname problem

[Adrian Blake]

Hi,
I used a default hostname when I setup my Ubuntu 20.04.
I now appears to have changed but only as my router see it and my pi-hole
see it. It has the name " ESP_9250A6 ".  I changed the hostname on my
machine but my router and pi-hole still see "ESP-9250A6" .
Why would this be so?
Adrian
