"The file is not a valid icon theme archive." - KDE Plasma 5 can't install one single icon theme

Figured it out.

  1. Download icon manually.
  2. Extract the file to a temporary folder.
  3. And move the folder (it should have an index.theme inside) to: ~/.local/share/icons or /usr/share/icons
  4. Enjoy.

There's a lot of misinformation on the Internet about the correct icon folder. And downloading icons using the System Settings is very unreliable.

    I have tried via the KDE Settings Icon theme installer & also the Manual way. I keep getting the The file is not a valid icon theme archive. message. Not one single theme has worked so far. Anyone has a way? The default themes supplied are worthy of Windows NT.

      What icon theme? How do you install it? What kind of file is the message referring?
