Hi @advocatux , I have tried the command proposed and works successfully. Thanks for your answer.

I have solved the issue. The fail was a media scanner corrupted database located in: /home/username/.cache/mediascanner-2.0/mediastore.db Once removed the file and rebooted the phone, new database was created succesfully. I left this topic because may be useful to other users with the same problem. Thanks to all the developers for keeping this project alive
