Ubuntu 2004 missing resolvconf package by default.

[upodroid]

Hello

The role doesn't check if resolvconf is installed on ubuntu-2004. Installing the package resolves the error.

Hi,

TBH I've no idea. My Moleule tests use a fresh installation of Ubuntu 20.04 and I didn't had this issue at any time there. I also can't find the usage of resolvconf command in any of my systemd journal's. Maybe you're using a WireGuard option that requires this tool to be installed or you've a very stripped down version of Ubuntu installed.

There are reports out there that suggests installing openresolv package in case of this error. But I don't see a reason to do so as systemd-resolved has everything needed in place which the default for Ubuntu 20.04.

Regards
