[solved] Why will hostname not get updated?

$ cat /etc/hosts 
# Static table lookup for hostnames.
# See hosts(5) for details.
127.0.0.1 localhost
::1 localhost

# 127.0.0.1 my_name123

And

$ hostname

my_name123

This has remained even after a reboot.

/etc/hosts != /etc/hostname

And localhost is not a valid hostname and will lead to all sorts of issues if that file leaves any conclusion towards your intention.
