Bug description:
  After grub crash during Ubuntu 18.04 LTS (Release:	18.04) installation I had probably partially installed system.
  I have fix problem with grub using boot-repair, but I'm still not able to run any Qt application.
  I have been trying to deinstall and reinstall Qt libs, and finally stacked on this:
