I replay to myself...

the problem was solved running the file as normal user and not as administrator.

Hi

I would like use "Oracle JDevelopper"  on my computer, so
I downloaded the "installer" of Jdeveloper from site of Oracle .

This is the page of Oracle for the download:
-------------- 
Oracle JDeveloper Studio Edition 12.2.1.2.0   This download is the complete version of JDeveloper with all the features. This is the recommended Download.

Important Note - both files are required for each platform to complete the installation.   Windows (2.1GB)file1, file2    Linux (2.1GB)file1, file2   Generic/Others(2.1GB)file1, file2
--------------

After I downloaded the two recommended files, I had them in the directory /home/ /Download of my computer.
I changed the attributes of them,   so I had

-rwxrwxrwx. 1 angelo_dev angelo_dev  302779189 May 27 11:59 jdev_suite_122120_linux64-2.zip
-rwxrwxrwx. 1 angelo_dev angelo_dev 2043993719 May 27 11:51 jdev_suite_122120_linux64.bin


After done this, I run the file .bin as administrator,
[root@localhost JDeveloper]# ./jdev_suite_122120_linux64.bin

The installation seemed to have started :
0%.......................................................................................100%
Launcher log file is /tmp/OraInstall2017-05-28_03-06-44PM/launcher2017-05-28_03-06-44PM.log.
Extracting the installer . . . . . Done
The current user is root or has superuser privilege.

but it was not finished successfully.   ....I got the following message

The Oracle Universal Installer cannot continue.
The log is located here: /tmp/OraInstall2017-05-28_03-06-44PM/launcher2017-05-28_03-06-44PM.log.


What happened wrong ??

What do do now ??
