In this post I am going to share the steps for installation of SQL Developer on Linux Mint OS or Ubuntu.

 SQL developer will require to jdk as pre-requisites.

 Steps:

 1. Install jdk 8 or above. 

 sudo apt-get install openjdk-8-jdk

 It will be installed in below folder

 /usr/lib/jvm/java-8-openjdk-amd64

 2. SQL Developer which we wil download from Oracle Website would in rpm format. I am going to use alien tool to covert it in debian(deb) format.

 sudo apt-get install -y alien

 3. Convert the SQL developer rpm to debain format.

 himanshu@himanshu-ThinkPad-T430 ~/Downloads $ ls -ltr sqldeveloper-19.2.1.247.2212.noarch.rpm
-rw-rw-r-- 1 himanshu himanshu 420128668 Sep 18 23:46 sqldeveloper-19.2.1.247.2212.noarch.rpm
himanshu@himanshu-ThinkPad-T430 ~/Downloads $ sudo alien sqldeveloper-19.2.1.247.2212.noarch.rpm

 Once done we can see below deb file.

 himanshu@himanshu-ThinkPad-T430 ~/Downloads $ ls -ltr sqldeveloper_19.2.1-248.2212_all.deb

 -rw-r--r-- 1 root root 416469574 Sep 19 00:02 sqldeveloper_19.2.1-248.2212_all.deb


4. Install SQL Developer package now.

or 

Run below command on terminal

himanshu@himanshu-ThinkPad-T430 ~/Downloads $ sudo dpkg -i sqldeveloper_19.2.1-248.2212_all.deb
