Re: Debian 12, setting hostname does not persist

Hello,
I've got a VPS through a2hosting it was running Debian 11 specifically
11.7. Long story short I just had to reinstall it after a hard week of
work so instead of doing it all over again on 11.7 I decided to
upgrade to 12.0. I used this:
https://www.makeuseof.com/upgrade-to-debian-12-bookworm-from-debian-11/
the upgrade itself went just fine. I set my time zone that stuck and
is persisting then went for the hostname, I am doing this via ssh, in
setting the hostname it won't persist through a reboot.
In the below output I've x-d out items like the device chasis ID and
the IP I've made it a 192.168.x.x address even tthough the actual
address is public.
The one thing I see and I don't know if this is related is when I
change the hostname with set-hostname hostnamectl -f and -i gives an
error.
#hostname

#hostname -f
server.example.com
#hostname -i

I've googled and not seen this as a problem, I am quite perplexed.
Suggestions welcome.
Thanks.
Dave.
I ran into a similar problem setting up some bananapi-m5's running
armbian as klipper interfaces to 3d printers. That hostname must exist
in the /etc/hosts file before it quits resetting the hostname to the
install default. It might be an armbian problem, but it does IMO rate a
check. So edit the hosts file first.
