arduino IDE does not find libraries

Upon fresh install of the arduino IDE on Kubuntu 19.10, I downloaded and extracted the MFRC522 library for RFID communication into the ~/sketchbook/libraries/ directory. No automatic library manager is available in my version of the IDE (2:1.0.5+dfsg2-4.1), unlike suggested in tutorials on importing libraries.

When I try to compile (click tick mark button) an example file from this library, it aborts compilation with the message:

DumpInfo.ino:38:21: fatal error: MFRC522.h: file or directory not found (translated)

The compiler seems to ignore the .h file in the library folder while being aware of the included Example code. The .h file is at ~/sketchbook/libraries/MFRC522/src/MFRC522.h, the Example code at ~/sketchbook/libraries/MFRC522/examples/DumpInfo/Dumpinfo.ino.

I reproduced this problem with another library (Blynk). I'd appreciate any help on this.

download the IDE from arduino.cc. the ancient version available over package managers can't work with libraries in 1.5 format – Juraj

As pointed out by @Juraj, the fault lies with the outdated IDE version shipped with the Ubuntu package sources. Installing from arduino.cc has helped, thanks!
