    I've had the same issue on 18.04 server virtual machine with GUI, so I can't say whether or not it's applicable to Desktop version, but I did have to install one of the packages ( specifically qtchooser ) to get qdbus.

    According to Ubuntu package search for bionic (18.04), these are the amd64 packages that do contain qdbus, among which:

    • qtchooser
    • qdbus-qt5 ( referenced by OP on an old post with no answer )
    • qdbus

    I'd recommend going with sudo apt install qtchooser since this is the same solution I've used. However, either of these 3 should work just fine.

    Sidenote: On Ubuntu server 18.04 with XFCE4 installed via repositories , installing qtchooser produced no effect, but qdbus-qt5 did. I suspect this has to do with certain dependencies that qdbus-qt5 pulls with it, which may have been installed in other instances. I'd recommend installing this package.
