I have the same issue and linux-image-4.15.0.189-generic did not solve it for me neither (downloaded from https://ubuntu.pkgs.org/18.04/ubuntu-proposed-main-amd64/linux-image-4.15.0-189-generic_4.15.0-189.200_amd64.deb.html).
I still have no WiFi, no control over sound, luminosity or whatsoever, and HDMI output doesn't work.
My device : Ubuntu 18.04.6 LTS Asus Zenbook UX410UF-GV028T Intel i7-8550U Intel UHD Graphics 620
I don't know how to change the tag to 'verification-failed-bionic' though...
