He estado instalando y borrando aplicaciones probando de todo, y no sé en qué momento me desaparecieron temas de MATE (por cierto, tengo Mint 18.2 con escritorio MATE). Buscando por la web encontré que podía tratarse de un problema de permisos, busqué la carpeta y le he otorgado a todos altos privilegios sobre la carpeta pero siguen sin aparecer los temas, subo capturas a ver que me dicen.
Acá lo que me aparece luego de introducir en la terminal ls -l /usr/share/themes
