Hostname change / Pending changes

Hi,

I changed a hostname on my RPI4 OMV machine. Applied changes.

Now it still asked me to apply pending changes, even if I've just done it probably 5-6 times already.

I have this:

Logged in through SSH and /etc/hostname shows the new name, but /etc/hosts show the old one.

I can log in to the web admin dashboard using both - old and new hostname.

Currently I'm on 6.6.0-2 (just upgraded from probably one version down.

Is the restart required to apply the changes permanently?

No special characters in the hostname.

Old name was "rpi4", new one is "omv" (as I have more rpi4s in the network and it became confusing)

The /var/lib/openmediavault/dirtymodules.json file shows this:

[
"avahi",
"postfix",
"hostname",
"hosts",
"systemd-networkd"
]

After applying changes (again!) I got this error info in the top right bell icon (sorry, the post was over 10000 chars, so I had to make pastebin link): https://pastebin.com/RCm3V4Ug

If not other option - I'll restart it and will see then.

This seems to be the problem. Can you find out some more information when running

systemctl start systemd-networkd.service netplan-wpa-wlan0.service netplan-ovs-cleanup.service

manually?

When run it again I didn't have the D-bus warning, but hangs up at the end (doesn't show the command prompt for a minute or two, the show this:

A dependency job for netplan-wpa-wlan0.service failed. See 'journalctl -xe' for details.

The same when using sudo before the command.

The result of journalctl -xe:

Aug 22 22:48:07 omv sudo[4318]:       pi : TTY=pts/0 ; PWD=/home/pi ; USER=root ; COMMAND=/usr/bin/systemctl start systemd-networkd.service netplan-wpa-wlan0.service netplan-ovs-cleanup.service

Aug 22 22:49:37 omv sudo[4318]: pam_unix(sudo:session): session closed for user root

Then applied pending changes and still have similar errors as previously.

Reboot didn't help.

Still get the same errors when try to apply pending changes.

Is it something related to the WLAN adaptor?

I use wired LAN only. Can I disable WLAN somehow?

Soma - my question was more like: Is the error related to the WLAN adaptor?

Will disable it anyway when back home later. Thanks. Don't need any of them.

I think it is the reason.

I think it must be something else as it seems like I have it already disabled (wifi and bt).

Any ideas guys?

Just to let you all know - when I've been asked to apply the changes again I clicked cancel or revert (cannot remember how it is called) and it doesn't show the notification any longer. Also the /var/lib/openmediavault/dirtymodules.json file is empty. And the hostname is the new hostname I set up a few days ago. So I guess all is as it should be.
