Generally for each version you try you need to install all the packages _except_ the "lowlatency" ones.
So:
linux-headers-4.19.0-041900_4.19.0-041900.201810221809_all.deb linux-headers-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb linux-image-unsigned-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb linux-modules-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
