Sql-server – Error 5123 when creating a database with the SQL Server on Linux

I followed the steps of this MS Guide and I managed to run a localdb and create a Testdb with this script:

CREATE DATABASE Test
ON
    (NAME='Test_DAT',
    FILENAME='/home/dlag/Documentos/Proyectos/BDtest/Test.mdf',
    SIZE=10,
    MAXSIZE=50,
    FILEGROWTH=5)
LOG ON
    (NAME='Test_Log',
    FILENAME='/home/dlag/Documentos/Proyectos/BDtest/Test.ldf',
    SIZE=5,
    MAXSIZE=25,
    FILEGROWTH=5);

GO
use Test;
GO

Time after, I try to create another db with the following script:

CREATE DATABASE BconDatos2
ON
    (NAME='BconDatos2_DAT',
    FILENAME='/home/dlag/Documentos/Proyectos/BDs/BiblioConDatos2/BconDatos2.mdf',
    SIZE=10,
    MAXSIZE=50,
    FILEGROWTH=5)
LOG ON
    (NAME='BconDatos2_Log',
    FILENAME='/home/dlag/Documentos/Proyectos/BDs/BiblioConDatos2/BconDatos2.ldf',
    SIZE=5,
    MAXSIZE=25,
    FILEGROWTH=5);

GO
use BconDatos2;

and I get this errors:

Msg 5123, Level 16, State 1, Line 4

AND SAYS(translated from Spanish):

The instruction CREATE FILE found OS error: 2(The system cannot find the file specified.) when trying to open or create the physical file.
'/home/dlag/Documentos/Proyectos/BDs/BiblioConDatos2/BconDatos2.mdf'.

Msg 1802, Level 16, State 4, Line 4

(translated from Spanish):

CREATE DATABASE error. Can not create some of the files in the list. See related errors

Total execution time: 00:00:00.081

On both DB I'm in master and the path for mdf and ldf files are previously created.

It's strange because in the script of 'Test' DB I can make SELECTS for Tables, but when I run:

SELECT Name from sys.Databases

This database doesn't appear, but another empty DB created later appears.

Anyway on 'BconDatos2' DB script I can't create DataBases…

Problems with permissions on scripts?
