When I create a new host with Ubuntu 17.10 I haven’t got problem, only with 18.04

it works, In the parameters of the OS, I remove minor version, there are only Major version and the name of the release.

But when I use Cosmic in release name in order to use 18.04 LTS, at the start of installation an error appear about kernel modules.

Do you say it works or it does not? I don’t see anything suspicious.
