(In reply to Nolan Leasy from comment #0)
> The repository at 'http://opensuse-guide.org/repo/openSUSE_Leap_15.0' is
> missing.  This is present for all previous Leap releases.
> 
> This repository is necessary to install the 'libdvdcss2' package.  
> 
> ==> The workaround, for now, is to add the corresponding repository for Leap
> 42.3.

> The missing repository can be added, but produces an error on refresh:

I have already contacted admin@opensuse-guide.org one week ago, but have not
got an answer yet. Please note that this is not an official opensuse repo.
