I created a live Kubuntu persistent installation using mkusb. This was the only tool that could create a working Kubuntu installation for my macbook. It works properly and changes are kept after the reboot, but with some exceptions: some properties set in the network manager are not saved at all. For instance if I try to add additional DNS addresses or set password for a VPN setup, those are not saved. Reboot is not needed to clear those props, just closing the dialog and reopening it and the prop is lost. Also when changing values the apply button is always disabled.
Anyone else experiencing the same on a live installation? Any way to set those properties persistently somehow?
