Unable to save /conf/openfire.xml - check that it is writable

can’t update 4.2.3 to 4.4.1, i always encounter this error. i have check permission to this file and it is writable.

Linux/Windows?

running on ubuntu 18.04

You shouldn’t be doing web setup again when doing an upgrade. How was 4.2.3 installed and how was you running it? Deb? How are you running 4.4.1 update?

it’s a fresh install of the 4.4.1 version. after finishing configuring openfire i always encounter this error.

How do you install? The easiest way is to use deb package and install it with:
sudo dpkg -i openfire.deb (replace with real package name)
This will create openfire group and a user who will own all openfire files, it will also install and run a service. After this you can open a browser and go to http://localhost:9090. There should not be the same error then.
