What is the best way to make the Debian desktop look like Ubuntu in Gnome Flashback session? I think is just 2 changes:
Install Ubuntu font and set it in Gnome Tweaks tool
Download the official Yaru theme (GTK theme and icons) and install it
Just do what you wrote, simple as that :)
Yaru instructions here: https://www.gnome-look.org/p/1252100/
Installation :
Just unzip the file and place it in your themes directory i.e. ~/.themes/ or /usr/share/themes/
Install gnome-tweak-tool sudo apt install gnome-tweak-tool
Select the theme as 'Yaru-light' or 'Yaru-dark'
Font :
Install this package
sudo apt-get install ttf-ubuntu-font-familyOpen Gnome tweak tool (Tweaks in apps) and select fonts tab on the left (if you do not have this program ->
sudo apt-get install gnome-tweak-tool). Apply the Ubuntu Regular and Ubuntu Mono Regular fonts with the sizes like in the image below :
