Error installing qt5.5 -opensource-linux-x64-5.5.1.run

Please read this:

Especially The N00b guide to installing software because:

  • You’ve very probably totally messed up your system
  • You’re in for a re-install

as KDE is on 5.15.2 on Manjaro and you’ve installed a 5.5 KDE .run file that cannot be uninstalled.

:scream:
