problems to load arduino clone CH340 in linux

hello, when loading any program I skip the following message:

Sketch uses 1,030 bytes (7%) of program storage space. Maximum is 14,336 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 1,015 bytes for local variables. Maximum is 1,024 bytes. /home/ariel/Descargas/arduino-1.6.0/hardware/tools/avr/bin/avrdude: error while loading shared libraries: libreadline.so.6: can not open shared object file: No such file or directory

never finish uploading the file to the micro.

Install the library. It should be in your distros repository.
