Arduino IDE 1.8.5, Ubuntu 17.10 - all libraries are wrong

Development Tools IDE 1.x
1

Arduino IDE 1.8.5 whines about my libraries. It says they are wrong. They used to be ok in Arduino IDE 1.5.8 in Ubuntu 14.04 before I installed the newer Ubuntu 17.10. What is wrong with the libraries now?

Is it something wrong in Ubuntu? What?
Is it something wrong in Arduino IDE? What?

Almost certainly those libraries were never ok. The difference is the old versions of the IDE didn't display a warning about invalid libraries. There's nothing wrong with your operating system or the Arduino IDE. If you look closely you can see there are actually only six warnings repeated multiple times.

There are three common causes of the invalid library warning:

  • You saved a sketch to the libraries folder. Sketches are only allowed in that folder as examples inside the folder of a valid library. Fix: move the sketch anywhere else other than the libraries folder.
  • Incorrect installation of a valid library. The library folder must be directly under the libraries folder, not in a subfolder. This means the library must have either a .h file or a library.properties file in its root folder. Fix: move the library folder to directly under the libraries folder.
  • Something that's neither library nor sketch in the libraries folder. Fix: move it somewhere else, anywhere other than the libraries folder.

Thank you! The six libraries were empty... I removed the folders and voila - the warnings about incorrect libraries are gone. Yippee!

I'm tempted to think he may have placed the contents of the folder that contained a library into the sketchbook/libraries folder, instead of placing the folder itself there (the opposite of what people more frequently do, ie, putting the library folder into another folder inside of sketchbook/libraries
