As per my understang try below steps :-

  1. Using Root try below steps

  2. Install sqldeveloper first

  3. Check the installation path of jdk installed in your system.

    /usr/lib/jvm/java-1.8.0-openjdk.x86_64

  4. Use any editor and add the above path to

    /opt/sqldeveloper/sqldeveloper/bin/sqldeveloper.conf

  5. SetJavaHome
