Thank you emk2203! Well spotted, armhf and amd64 packages of base-files are almost architecture independent except that locale-check. I will check the current and the previous version of the amd64 package in order to see the changes and decide if it's worth building the armhf package myself via your solution. Maybe we will get an update from Armbian, on https://www.armbian.com/odroid-xu4/ I see that ubuntu noble is (still) supported.
