I have installed the Plata Theme via Budgie Themes app. In the themes app, Plata theme shows as installed and ready to apply.
But the theme is not in the /themes or /.themes folder, neither is it listed in the theme options of the settings. There is a ppa tista/plata-theme.
Is there anything else to do, to make it work?
Do remember to logout and login after installing themes, icons and applets.
Global themes are installed to /usr/share/themes.
Did log out and back in and restart the computer. Still to no avail.
What version of UB are you using?
I am using Ubuntu Budgie 18.10, on a Dell Laptop.
As you can see - I applied plata (hit the apply button) just fine on my 18.10 VM - and plata is visible
No doubt it is visible on your machine. Now look at mine :
What happens if you run
sudo apt update && sudo apt dist-upgrade && sudo apt install --reinstall plata-theme
(logout and login if there are no errors or warnings from the above)?
This did the trick. Many thanks for your quick response.
