I just installed the cinnamon desktop environment on Ubuntu 19.04. The cinnamon themes that were installed by default on 18.04 don't appear to be installed by default on 19.04. Where can I find them?
I'm specifically looking to use the Bluebird window borders and the Blue Menta desktop theme.
The theme settings application in cinnamon has an empty menu for window borders. Not even the active theme is listed there.
The only desktop theme that's present is the stock "cinnamon" theme.
Here's a screenshot of the empty menu.
