I'm using Faenza icon theme on Ubuntu, specifically its Faenza-Darkest version for dark backgrounds (such as Ambiance theme). After upgrading from 18.04 to 19.04 some icons seem broken. Please see the screenshot:
Instead of beige folder icons, I get these dull grey ones. I tried re-installing Faenza, but its PPA seems to be down and Faenza is missing from the official Ubunbu PPAs.
How can I fix my icon theme?
