I have Ubuntu 20.04 LTS standard desktop installation:
Blurb from Ubuntu blog:
“The Ubuntu Desktop team have worked closely with the upstream GNOME developers and the wider community to deliver a solid GNOME desktop experience for our users. Thereby, joining our friends in the Debian project to update packages to the latest GNOME software packages.”
Are they lying?
EDIT
The article I quoted, https://ubuntu.com/blog/whats-new-in-ubuntu-desktop-20-04-lts, shows screenshot with the icons I have, but they also show a video with icons you’ve shown. I have no clue what is going on here.
EDIT
To get the icons you’ve shown, one has to use Tweak Tool and change icons from Yaru to Adwaita.
