Como configurar product.conf no sqldeveloper?

Olá pessoal, estou com problemas para configurar o caminho da pasta do JDK no product.conf do sqldeveloper.
Baixei o pacote rpm e converti pra .deb com o alien e instalei via dpkg, deu tudo certo.
Porém quando executo o sqldeveloper no terminal, retorna o seguinte:

root@kali:/# sqldeveloper



 Oracle SQL Developer

Type the full pathname of a JDK installation (or Ctrl-C to quit), the path will be stored in /root/.sqldeveloper/4.1.0/product.conf 

Estou com o openjdk-8 instalado na máquina e coloquei o caminho no product.conf da seguinte maneira:

##############################################################################

#

# The format of this file is:

#

# Directive  Value

#

# with one or more spaces between the directive and the value. This file

# can be in either UNIX or DOS format for end of line terminators. Use UNIX

# style '/' path separators, although on Windows some directives, such as

# SetJavaHome, can take '\' path separators.

#

##############################################################################



#

# By default, the product launcher will search for a JDK to use, and if none

# can be found, it will ask for the location of a JDK and store its location

# in this file. If a particular JDK should be used instead, uncomment the

# line below and set the path to your preferred JDK.

#



SetJavaHome /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/



#

# Specify the initial size, in bytes, of the memory allocation pool. This

# value must be a multiple of 1024 greater than 1MB. Append the letter k............ 

Mesmo assim o retorno na execução do comando sqldeveloper é o mesmo do inicio.
Preciso especificar o caminho do jdk em mais algum lugar?
