To Reproduce

1. Install yaru-theme
2. Using GNOME Desktop, open Gnome Tweaks and on the Appearance page look for Yaru in Shell theme selection.

Hmm, I don't personally use GNOME, but I guess you could try passing the gnome-shell option (-Dgnome-shell I think) to the meson flags somehow: source

Seems like it's really just a missing symlink. I managed to fix it. It also does not affect master, only 20.03.

[lourkeur]

Note that the Yaru-Dark gnome-shell theme is not present in this package either so you might just want to install yaru-theme from the unstable channel and be done with it.

91901 : Thanks @lourkeur !

I wonder why master is not affected. Is it because of some change between Yaru 19 and Yaru 20?

[lourkeur]

@alexeymuranov Yes, upstream added a script to make those links in 20.04.1 and no sooner.
