Hi,

just installing Qt 5.12 would break the dependency trees of Qt
related packages from official Ubuntu 18.04 repositories.

You could test if a snap does the job,
https://snapcraft.io/barrier
https://snapcraft.io/barrier-kvm
or you could update your Ubuntu release to at least 18.10,
https://packages.ubuntu.com/search?suite=cosmic&arch=any&searchon=names&keywords=barrier
It is build against Qt 5.11.

Regards,
Ralf
