Как заставить версию qt быть установленной

После последнего обновления qt у меня возник конфликт между версиями qt. Часть библиотек qt происходит из репозитория Ubuntu Xenial, а другая часть - из неона Xenial. Я больше не могу запускать kde из-за этого конфликта.

Ubuntu xenial использует qt 5.11.1 и неон qt 5.11.0. Поэтому я хотел бы понизить всю мою библиотеку qt до 5.11.0

Заранее благодарю за любые подсказки, которые вы можете предоставить.
